       * Converts a callback API to a function that returns an Observable.
       *
       * <span class="informal">Give it a function `f` of type `f(x, callback)` and
       * it will return a function `g` that when called as `g(x)` will output an
       * Observable.</span>
       *
       * `bindCallback` is not an operator because its input and output are not
       * Observables. The input is a function `func` with some parameters, but the
       * last parameter must be a callback function that `func` calls when it is
       * done.
       *
       * The output of `bindCallback` is a function that takes the same parameters
       * as `func`, except the last one (the callback). When the output function
       * is called with arguments, it will return an Observable. If `func` function
       * calls its callback with one argument, the Observable will emit that value.
       * If on the other hand callback is called with multiple values, resulting
       * Observable will emit an array with these arguments.
       *
       * It is very important to remember, that input function `func` is not called
       * when output function is, but rather when Observable returned by output
       * function is subscribed. This means if `func` makes AJAX request, that request
       * will be made every time someone subscribes to resulting Observable, but not before.
       *
       * Optionally, selector function can be passed to `bindObservable`. That function
       * takes the same arguments as callback, and returns value
       * that will be emitted by Observable instead of callback parameters themselves.
       * Even though by default multiple arguments passed to callback appear in the stream as array,
       * selector function will be called with arguments directly, just as callback would.
       * This means you can imagine default selector (when one is not provided explicitly)
       * as function that aggregates all its arguments into array, or simply returns first argument,
       * if there is only one.
       *
       * Last optional parameter - {@link Scheduler} - can be used to control when call
       * to `func` happens after someone subscribes to Observable, as well as when results
       * passed to callback will be emitted. By default subscription to Observable calls `func`
       * synchronously, but using `Scheduler.async` as last parameter will defer call to input function,
       * just like wrapping that call in `setTimeout` with time `0` would. So if you use async Scheduler
       * and call `subscribe` on output Observable, all function calls that are currently executing,
       * will end before `func` is invoked.
       *
       * When it comes to emitting results passed to callback, by default they are emitted
       * immediately after `func` invokes callback. In particular, if callback is called synchronously,
       * then subscription to resulting Observable will call `next` function synchronously as well.
       * If you want to defer that call, using `Scheduler.async` will, again, do the job.
       * This means that by using `Scheduler.async` you can, in a sense, ensure that `func`
       * always calls its callback asynchronously, thus avoiding terrifying Zalgo.
       *
       * Note that Observable created by output function will always emit only one value
       * and then complete right after. Even if `func` calls callback multiple times, values from
       * second and following calls will never appear in the stream. If you need to
       * listen for multiple calls, you probably want to use {@link fromEvent} or
       * {@link fromEventPattern} instead.
       *
       * If `func` depends on some context (`this` property), that context will be set
       * to the same context that output function has at call time. In particular, if `func`
       * is called as method of some object, in order to preserve proper behaviour,
       * it is recommended to set context of output function to that object as well,
       * provided `func` is not already bound.
       *
       * If input function calls its callback in "node style" (i.e. first argument to callback is
       * optional error parameter signaling whether call failed or not), {@link bindNodeCallback}
       * provides convenient error handling and probably is a better choice.
       * `bindCallback` will treat such functions without any difference and error parameter
       * (whether passed or not) will always be interpreted as regular callback argument.
       *
       *
       * @example <caption>Convert jQuery's getJSON to an Observable API</caption>
       * // Suppose we have jQuery.getJSON('/my/url', callback)
       * var getJSONAsObservable = Rx.Observable.bindCallback(jQuery.getJSON);
       * var result = getJSONAsObservable('/my/url');
       * result.subscribe(x => console.log(x), e => console.error(e));
       *
       *
       * @example <caption>Receive array of arguments passed to callback</caption>
       * someFunction((a, b, c) => {
       *   console.log(a); // 5
       *   console.log(b); // 'some string'
       *   console.log(c); // {someProperty: 'someValue'}
       * });
       *
       * const boundSomeFunction = Rx.Observable.bindCallback(someFunction);
       * boundSomeFunction().subscribe(values => {
       *   console.log(values) // [5, 'some string', {someProperty: 'someValue'}]
       * });
       *
       *
       * @example <caption>Use bindCallback with selector function</caption>
       * someFunction((a, b, c) => {
       *   console.log(a); // 'a'
       *   console.log(b); // 'b'
       *   console.log(c); // 'c'
       * });
       *
       * const boundSomeFunction = Rx.Observable.bindCallback(someFunction, (a, b, c) => a + b + c);
       * boundSomeFunction().subscribe(value => {
       *   console.log(value) // 'abc'
       * });
       *
       *
       * @example <caption>Compare behaviour with and without async Scheduler</caption>
       * function iCallMyCallbackSynchronously(cb) {
       *   cb();
       * }
       *
       * const boundSyncFn = Rx.Observable.bindCallback(iCallMyCallbackSynchronously);
       * const boundAsyncFn = Rx.Observable.bindCallback(iCallMyCallbackSynchronously, null, Rx.Scheduler.async);
       *
       * boundSyncFn().subscribe(() => console.log('I was sync!'));
       * boundAsyncFn().subscribe(() => console.log('I was async!'));
       * console.log('This happened...');
       *
       * // Logs:
       * // I was sync!
       * // This happened...
       * // I was async!
       *
       *
       * @example <caption>Use bindCallback on object method</caption>
       * const boundMethod = Rx.Observable.bindCallback(someObject.methodWithCallback);
       * boundMethod.call(someObject) // make sure methodWithCallback has access to someObject

       * callback arguments. It works similarly to {@link bindCallback} selector, but
       * Node.js-style error argument will never be passed to that function.
       *
       * Note that `func` will not be called at the same time output function is,
       * but rather whenever resulting Observable is subscribed. By default call to
       * `func` will happen synchronously after subscription, but that can be changed
       * with proper {@link Scheduler} provided as optional third parameter. Scheduler
       * can also control when values from callback will be emitted by Observable.
       * To find out more, check out documentation for {@link bindCallback}, where
       * Scheduler works exactly the same.
       *
       * As in {@link bindCallback}, context (`this` property) of input function will be set to context
       * of returned function, when it is called.
       *
       * After Observable emits value, it will complete immediately. This means
       * even if `func` calls callback again, values from second and consecutive
       * calls will never appear on the stream. If you need to handle functions
       * that call callbacks multiple times, check out {@link fromEvent} or
       * {@link fromEventPattern} instead.
       *
       * Note that `bindNodeCallback` can be used in non-Node.js environments as well.
       * "Node.js-style" callbacks are just a convention, so if you write for
       * browsers or any other environment and API you use implements that callback style,
       * `bindNodeCallback` can be safely used on that API functions as well.
       *
       * Remember that Error object passed to callback does not have to be an instance
       * of JavaScript built-in `Error` object. In fact, it does not even have to an object.
       * Error parameter of callback function is interpreted as "present", when value
       * of that parameter is truthy. It could be, for example, non-zero number, non-empty
       * string or boolean `true`. In all of these cases resulting Observable would error
       * with that value. This means usually regular style callbacks will fail very often when
       * `bindNodeCallback` is used. If your Observable errors much more often then you
       * would expect, check if callback really is called in Node.js-style and, if not,
       * switch to {@link bindCallback} instead.
       *
       * Note that even if error parameter is technically present in callback, but its value
       * is falsy, it still won't appear in array emitted by Observable or in selector function.
       *
       *
       * @example <caption>Read a file from the filesystem and get the data as an Observable</caption>
       * import * as fs from 'fs';
       * var readFileAsObservable = Rx.Observable.bindNodeCallback(fs.readFile);
       * var result = readFileAsObservable('./roadNames.txt', 'utf8');

   * Combines multiple Observables to create an Observable whose values are
   * calculated from the latest values of each of its input Observables.
   *
   * <span class="informal">Whenever any input Observable emits a value, it
   * computes a formula using the latest values from all the inputs, then emits
   * the output of that formula.</span>
   *
   * <img src="./img/combineLatest.png" width="100%">
   *
   * `combineLatest` combines the values from all the Observables passed as
   * arguments. This is done by subscribing to each Observable in order and,
   * whenever any Observable emits, collecting an array of the most recent
   * values from each Observable. So if you pass `n` Observables to operator,
   * returned Observable will always emit an array of `n` values, in order
   * corresponding to order of passed Observables (value from the first Observable
   * on the first place and so on).
   *
   * Static version of `combineLatest` accepts either an array of Observables
   * or each Observable can be put directly as an argument. Note that array of
   * Observables is good choice, if you don't know beforehand how many Observables
   * you will combine. Passing empty array will result in Observable that
   * completes immediately.
   *
   * To ensure output array has always the same length, `combineLatest` will
   * actually wait for all input Observables to emit at least once,
   * before it starts emitting results. This means if some Observable emits
   * values before other Observables started emitting, all that values but last
   * will be lost. On the other hand, is some Observable does not emit value but
   * completes, resulting Observable will complete at the same moment without
   * emitting anything, since it will be now impossible to include value from
   * completed Observable in resulting array. Also, if some input Observable does
   * not emit any value and never completes, `combineLatest` will also never emit
   * and never complete, since, again, it will wait for all streams to emit some
   * value.
   *
   * If at least one Observable was passed to `combineLatest` and all passed Observables
   * emitted something, resulting Observable will complete when all combined
   * streams complete. So even if some Observable completes, result of
   * `combineLatest` will still emit values when other Observables do. In case
   * of completed Observable, its value from now on will always be the last
   * emitted value. On the other hand, if any Observable errors, `combineLatest`
   * will error immediately as well, and all other Observables will be unsubscribed.
   *
   * `combineLatest` accepts as optional parameter `project` function, which takes
   * as arguments all values that would normally be emitted by resulting Observable.
   * `project` can return any kind of value, which will be then emitted by Observable
   * instead of default array. Note that `project` does not take as argument that array
   * of values, but values themselves. That means default `project` can be imagined
   * as function that takes all its arguments and puts them into an array.
   *
   *
   * @example <caption>Combine two timer Observables</caption>
   * const firstTimer = Rx.Observable.timer(0, 1000); // emit 0, 1, 2... after every second, starting from now
   * const secondTimer = Rx.Observable.timer(500, 1000); // emit 0, 1, 2... after every second, starting 0,5s from now
   * const combinedTimers = Rx.Observable.combineLatest(firstTimer, secondTimer);

   * // Logs
   * // [0, 0] after 0.5s
   * // [1, 0] after 1s
   * // [1, 1] after 1.5s
   * // [2, 1] after 2s
   *
   *
   * @example <caption>Combine an array of Observables</caption>
   * const observables = [1, 5, 10].map(
   *   n => Rx.Observable.of(n).delay(n * 1000).startWith(0) // emit 0 and then emit n after n seconds

       * `timer` returns an Observable that emits an infinite sequence of ascending
       * integers, with a constant interval of time, `period` of your choosing
       * between those emissions. The first emission happens after the specified
       * `initialDelay`. The initial delay may be a {@link Date}. By default, this
       * operator uses the `async` IScheduler to provide a notion of time, but you
       * may pass any IScheduler to it. If `period` is not specified, the output
       * Observable emits only one value, `0`. Otherwise, it emits an infinite
       * sequence.
       *
       * @example <caption>Emits ascending numbers, one every second (1000ms), starting after 3 seconds</caption>
       * var numbers = Rx.Observable.timer(3000, 1000);
       * numbers.subscribe(x => console.log(x));

       * @example <caption>Emits one number after five seconds</caption>
       * var numbers = Rx.Observable.timer(5000);
       * numbers.subscribe(x => console.log(x));

       * @see {@link interval}

       * @param {number|Date} initialDelay The initial delay time to wait before
       * emitting the first value of `0`.
       * @param {number} [period] The period of time between emissions of the
       * subsequent numbers.
       * @param {Scheduler} [scheduler=async] The IScheduler to use for scheduling
       * the emission of values, and providing a notion of "time".

   * check for equality with previously projected values. If a keySelector function is not provided, it will use each value from the

   *
   * In JavaScript runtimes that support `Set`, this operator will use a `Set` to improve performance of the distinct value checking.

   * In other runtimes, this operator will use a minimal implementation of `Set` that relies on an `Array` and `indexOf` under the
   * hood, so performance will degrade as more values are checked for distinction. Even in newer browsers, a long-running `distinct`
   * use might result in memory leaks. To help alleviate this in some scenarios, an optional `flushes` parameter is also provided so
   * that the internal `Set` can be "flushed", basically clearing it of values.

   * When any of the provided Observable emits an complete or error notification, it immediately subscribes to the next one

   *
   * <img src="./img/onErrorResumeNext.png" width="100%">
   *
   * `onErrorResumeNext` is an operator that accepts a series of Observables, provided either directly as
   * arguments or as an array. If no single Observable is provided, returned Observable will simply behave the same
   * as the source.
   *
   * `onErrorResumeNext` returns an Observable that starts by subscribing and re-emitting values from the source Observable.
   * When its stream of values ends - no matter if Observable completed or emitted an error - `onErrorResumeNext`
   * will subscribe to the first Observable that was passed as an argument to the method. It will start re-emitting
   * its values as well and - again - when that stream ends, `onErrorResumeNext` will proceed to subscribing yet another
   * Observable in provided series, no matter if previous Observable completed or ended with an error. This will
   * be happening until there is no more Observables left in the series, at which point returned Observable will
   * complete - even if the last subscribed stream ended with an error.
   *
   * `onErrorResumeNext` can be therefore thought of as version of {@link concat} operator, which is more permissive
   * when it comes to the errors emitted by its input Observables. While `concat` subscribes to the next Observable
   * in series only if previous one successfully completed, `onErrorResumeNext` subscribes even if it ended with
   * an error.
   *
   * Note that you do not get any access to errors emitted by the Observables. In particular do not
   * expect these errors to appear in error callback passed to {@link subscribe}. If you want to take
   * specific actions based on what error was emitted by an Observable, you should try out {@link catch} instead.
   *
   *
   * @example <caption>Subscribe to the next Observable after map fails</caption>
   * Rx.Observable.of(1, 2, 3, 0)
   *   .map(x => {
   *       if (x === 0) { throw Error(); }
           return 10 / x;
   *   })
   *   .onErrorResumeNext(Rx.Observable.of(1, 2, 3))
   *   .subscribe(
   *     val => console.log(val),
   *     err => console.log(err),          // Will never be called.
   *     () => console.log('that\'s it!')
   *   );
   *
   * // Logs:
   * // 10
   * // 5
   * // 3.3333333333333335
   * // 1
   * // 2

   * observable emits before completing, the returned observable will emit `false` and complete. If one observable never
   * completes or emits after the other complets, the returned observable will never complete.

   *
   * `concat` joins multiple Observables together, by subscribing to them one at a time and
   * merging their results into the output Observable. You can pass either an array of
   * Observables, or put them directly as arguments. Passing an empty array will result
   * in Observable that completes immediately.
   *
   * `concat` will subscribe to first input Observable and emit all its values, without
   * changing or affecting them in any way. When that Observable completes, it will
   * subscribe to then next Observable passed and, again, emit its values. This will be
   * repeated, until the operator runs out of Observables. When last input Observable completes,
   * `concat` will complete as well. At any given moment only one Observable passed to operator
   * emits values. If you would like to emit values from passed Observables concurrently, check out
   * {@link merge} instead, especially with optional `concurrent` parameter. As a matter of fact,
   * `concat` is an equivalent of `merge` operator with `concurrent` parameter set to `1`.
   *
   * Note that if some input Observable never completes, `concat` will also never complete
   * and Observables following the one that did not complete will never be subscribed. On the other
   * hand, if some Observable simply completes immediately after it is subscribed, it will be
   * invisible for `concat`, which will just move on to the next Observable.
   *
   * If any Observable in chain errors, instead of passing control to the next Observable,
   * `concat` will error immediately as well. Observables that would be subscribed after
   * the one that emitted error, never will.
   *
   * If you pass to `concat` the same Observable many times, its stream of values
   * will be "replayed" on every subscription, which means you can repeat given Observable
   * as many times as you like. If passing the same Observable to `concat` 1000 times becomes tedious,
   * you can always use {@link repeat}.

   * Errors if Observable does not emit a value in given time span.
   *
   * <span class="informal">Timeouts on Observable that doesn't emit values fast enough.</span>
   *
   * <img src="./img/timeout.png" width="100%">
   *
   * `timeout` operator accepts as an argument either a number or a Date.
   *
   * If number was provided, it returns an Observable that behaves like a source
   * Observable, unless there is a period of time where there is no value emitted.
   * So if you provide `100` as argument and first value comes after 50ms from
   * the moment of subscription, this value will be simply re-emitted by the resulting
   * Observable. If however after that 100ms passes without a second value being emitted,
   * stream will end with an error and source Observable will be unsubscribed.
   * These checks are performed throughout whole lifecycle of Observable - from the moment
   * it was subscribed to, until it completes or errors itself. Thus every value must be
   * emitted within specified period since previous value.
   *
   * If provided argument was Date, returned Observable behaves differently. It throws
   * if Observable did not complete before provided Date. This means that periods between
   * emission of particular values do not matter in this case. If Observable did not complete
   * before provided Date, source Observable will be unsubscribed. Other than that, resulting
   * stream behaves just as source Observable.
   *
   * `timeout` accepts also a Scheduler as a second parameter. It is used to schedule moment (or moments)
   * when returned Observable will check if source stream emitted value or completed.
   *
   * @example <caption>Check if ticks are emitted within certain timespan</caption>
   * const seconds = Rx.Observable.interval(1000);
   *
   * seconds.timeout(1100) // Let's use bigger timespan to be safe,
   *                       // since `interval` might fire a bit later then scheduled.
   * .subscribe(
   *     value => console.log(value), // Will emit numbers just as regular `interval` would.
   *     err => console.log(err) // Will never be called.
   * );
   *
   * seconds.timeout(900).subscribe(
   *     value => console.log(value), // Will never be called.
   *     err => console.log(err) // Will emit error before even first value is emitted,
   *                             // since it did not arrive within 900ms period.
   * );
   *
   * @example <caption>Use Date to check if Observable completed</caption>
   * const seconds = Rx.Observable.interval(1000);
   *
   * seconds.timeout(new Date("December 17, 2020 03:24:00"))
   * .subscribe(
   *     value => console.log(value), // Will emit values as regular `interval` would
   *                                  // until December 17, 2020 at 03:24:00.
   *     err => console.log(err) // On December 17, 2020 at 03:24:00 it will emit an error,
   *                             // since Observable did not complete by then.
   * );
   *
   * @see {@link timeoutWith}
   *
   * @param {number|Date} due Number specifying period within which Observable must emit values

   *
   * Re-emits all notifications from source Observable with specified scheduler.
   *
   * <span class="informal">Ensure a specific scheduler is used, from outside of an Observable.</span>
   *
   * `observeOn` is an operator that accepts a scheduler as a first parameter, which will be used to reschedule
   * notifications emitted by the source Observable. It might be useful, if you do not have control over
   * internal scheduler of a given Observable, but want to control when its values are emitted nevertheless.
   *
   * Returned Observable emits the same notifications (nexted values, complete and error events) as the source Observable,
   * but rescheduled with provided scheduler. Note that this doesn't mean that source Observables internal
   * scheduler will be replaced in any way. Original scheduler still will be used, but when the source Observable emits
   * notification, it will be immediately scheduled again - this time with scheduler passed to `observeOn`.
   * An anti-pattern would be calling `observeOn` on Observable that emits lots of values synchronously, to split
   * that emissions into asynchronous chunks. For this to happen, scheduler would have to be passed into the source
   * Observable directly (usually into the operator that creates it). `observeOn` simply delays notifications a
   * little bit more, to ensure that they are emitted at expected moments.
   *
   * As a matter of fact, `observeOn` accepts second parameter, which specifies in milliseconds with what delay notifications
   * will be emitted. The main difference between {@link delay} operator and `observeOn` is that `observeOn`
   * will delay all notifications - including error notifications - while `delay` will pass through error
   * from source Observable immediately when it is emitted. In general it is highly recommended to use `delay` operator
   * for any kind of delaying of values in the stream, while using `observeOn` to specify which scheduler should be used
   * for notification emissions in general.
   *
   * @example <caption>Ensure values in subscribe are called just before browser repaint.</caption>
   * const intervals = Rx.Observable.interval(10); // Intervals are scheduled
   *                                               // with async scheduler by default...
   *
   * intervals
   * .observeOn(Rx.Scheduler.animationFrame)       // ...but we will observe on animationFrame
   * .subscribe(val => {                           // scheduler to ensure smooth animation.
   *   someDiv.style.height = val + 'px';
   * });
   *
   * @see {@link delay}
   *
   * @param {IScheduler} scheduler Scheduler that will be used to reschedule notifications from source Observable.
   * @param {number} [delay] Number of milliseconds that states with what delay every notification should be rescheduled.
   * @return {Observable<T>} Observable that emits the same notifications as the source Observable,
   * but with provided scheduler.

       *
       * <span class="informal">Use it when you have all these Observables, but still nothing is happening.</span>
       *
       * `subscribe` is not a regular operator, but a method that calls Observable's internal `subscribe` function. It
       * might be for example a function that you passed to a {@link create} static factory, but most of the time it is
       * a library implementation, which defines what and when will be emitted by an Observable. This means that calling
       * `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often
       * thought.
       *
       * Apart from starting the execution of an Observable, this method allows you to listen for values
       * that an Observable emits, as well as for when it completes or errors. You can achieve this in two
       * following ways.
       *
       * The first way is creating an object that implements {@link Observer} interface. It should have methods
       * defined by that interface, but note that it should be just a regular JavaScript object, which you can create
       * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular do
       * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also
       * that your object does not have to implement all methods. If you find yourself creating a method that doesn't
       * do anything, you can simply omit it. Note however, that if `error` method is not provided, all errors will
       * be left uncaught.
       *
       * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.
       * This means you can provide three functions as arguments to `subscribe`, where first function is equivalent
       * of a `next` method, second of an `error` method and third of a `complete` method. Just as in case of Observer,
       * if you do not need to listen for something, you can omit a function, preferably by passing `undefined` or `null`,
       * since `subscribe` recognizes these functions by where they were placed in function call. When it comes
       * to `error` function, just as before, if not provided, errors emitted by an Observable will be thrown.
       *
       * Whatever style of calling `subscribe` you use, in both cases it returns a Subscription object.
       * This object allows you to call `unsubscribe` on it, which in turn will stop work that an Observable does and will clean
       * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback
       * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.
       *
       * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.
       * It is an Observable itself that decides when these functions will be called. For example {@link of}
       * by default emits all its values synchronously. Always check documentation for how given Observable
       * will behave when subscribed and if its default behavior can be modified with a {@link Scheduler}.
       *
       * @example <caption>Subscribe with an Observer</caption>
       * const sumObserver = {
       *   sum: 0,
       *   next(value) {
       *     console.log('Adding: ' + value);
       *     this.sum = this.sum + value;
       *   },
       *   error() { // We actually could just remove this method,
       *   },        // since we do not really care about errors right now.
       *   complete() {
       *     console.log('Sum equals: ' + this.sum);
       *   }
       * };
       *
       * Rx.Observable.of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.
       * .subscribe(sumObserver);
       *
       * // Logs:

 *
 * Asap Scheduler
 *
 * <span class="informal">Perform task as fast as it can be performed asynchronously</span>
 *
 * `asap` scheduler behaves the same as {@link async} scheduler when you use it to delay task
 * in time. If however you set delay to `0`, `asap` will wait for current synchronously executing
 * code to end and then it will try to execute given task as fast as possible.
 *
 * `asap` scheduler will do its best to minimize time between end of currently executing code
 * and start of scheduled task. This makes it best candidate for performing so called "deferring".
 * Traditionally this was achieved by calling `setTimeout(deferredTask, 0)`, but that technique involves
 * some (although minimal) unwanted delay.
 *
 * Note that using `asap` scheduler does not necessarily mean that your task will be first to process
 * after currently executing code. In particular, if some task was also scheduled with `asap` before,
 * that task will execute first. That being said, if you need to schedule task asynchronously, but
 * as soon as possible, `asap` scheduler is your best bet.
 *
 * @example <caption>Compare async and asap scheduler</caption>
 *
 * Rx.Scheduler.async.schedule(() => console.log('async')); // scheduling 'async' first...
 * Rx.Scheduler.asap.schedule(() => console.log('asap'));
 *
 * // Logs:
 * // "asap"
 * // "async"
 * // ... but 'asap' goes first!

 * executing synchronous code ends (commonly achieved by `setTimeout(deferredTask, 0)`),
 * better choice will be the {@link asap} scheduler.
