/**
* 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);

* boundAsyncFn().subscribe(() => console.log('I was async!'));
* console.log('This happened...');
*
* // Logs:
* // I was sync!
* // This happened...
* // I was async!

/**
* Converts a Node.js-style callback API to a function that returns an
* Observable.
*
* <span class="informal">It's just like {@link bindCallback}, but the
* callback is expected to be of type `callback(error, result)`.</span>
*
* `bindNodeCallback` 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 callback function is expected to follow Node.js conventions,
* where the first argument to the callback is an error object, signaling
* whether call was successful. If that object is passed to callback, it means
* something went wrong.
*
* The output of `bindNodeCallback` 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` calls its callback with error parameter present, Observable will
* error with that value as well. If error parameter is not passed, Observable will emit
* second parameter. If there are more parameters (third and so on),
* Observable will emit an array with all arguments, except first error argument.
*
* Optionally `bindNodeCallback` accepts selector function, which allows you to
* make resulting Observable emit value computed by selector, instead of regular
* 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');
* result.subscribe(x => console.log(x), e => console.error(e));
*
*
* @example <caption>Use on function calling callback with multiple arguments</caption>
* someFunction((err, a, b) => {
* console.log(err); // null
* console.log(a); // 5
* console.log(b); // "some string"
* });
* var boundSomeFunction = Rx.Observable.bindNodeCallback(someFunction);
* boundSomeFunction()
* .subscribe(value => {
* console.log(value); // [5, "some string"]
* });
*
*
* @example <caption>Use with selector function</caption>
* someFunction((err, a, b) => {
* console.log(err); // undefined
* console.log(a); // "abc"
* console.log(b); // "DEF"
* });
* var boundSomeFunction = Rx.Observable.bindNodeCallback(someFunction, (a, b) => a + b);
* boundSomeFunction()
* .subscribe(value => {
* console.log(value); // "abcDEF"
* });
*
*
* @example <caption>Use on function calling callback in regular style</caption>

* 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);
* combinedTimers.subscribe(value => console.log(value));
* // 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
* );
* const combined = Rx.Observable.combineLatest(observables);
* combined.subscribe(value => console.log(value));
* // Logs
* // [0, 0, 0] immediately
* // [1, 0, 0] after 1s
* // [1, 5, 0] after 5s
* // [1, 5, 10] after 10s
*
*
* @example <caption>Use project function to dynamically calculate the Body-Mass Index</caption>
* var weight = Rx.Observable.of(70, 72, 76, 79, 75);
* var height = Rx.Observable.of(1.76, 1.77, 1.78);
* var bmi = Rx.Observable.combineLatest(weight, height, (w, h) => w / (h * h));

* Observable.

/**
* Returns an Observable that emits all items emitted by the source Observable that are distinct by comparison from previous items.
*
* If a keySelector function is provided, then it will project each value from the source observable into a new value that it will
* check for equality with previously projected values. If a keySelector function is not provided, it will use each value from the
* source observable directly with an equality check against previous values.
*
* 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.
*
* @example <caption>A simple example with numbers</caption>
* Observable.of(1, 1, 2, 2, 2, 1, 2, 3, 4, 3, 2, 1)
* .distinct()
* .subscribe(x => console.log(x)); // 1, 2, 3, 4
*
* @example <caption>An example using a keySelector function</caption>
* interface Person {
* age: number,
* name: string
* }
*
* Observable.of<Person>(
* { age: 4, name: 'Foo'},
* { age: 7, name: 'Bar'},
* { age: 5, name: 'Foo'})
* .distinct((p: Person) => p.name)

* When any of the provided Observable emits an complete or error notification, it immediately subscribes to the next one
* that was passed.
*
* <span class="informal">Execute series of Observables no matter what, even if it means swallowing errors.</span>
*
* <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
* // 3
* // "that's it!"
*
* @see {@link concat}
* @see {@link catch}
*
* @param {...ObservableInput} observables Observables passed either directly or as an array.
* @return {Observable} An Observable that emits values from source Observable, but - if it errors - subscribes

*
* <img src="./img/concat.png" width="100%">
*
* `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}.
*
* @example <caption>Concatenate a timer counting from 0 to 3 with a synchronous sequence from 1 to 10</caption>

*
* <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
* or Date specifying before when Observable should complete
* @param {Scheduler} [scheduler] Scheduler controlling when timeout checks occur.

/**
*
* 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.

/**
* Invokes an execution of an Observable and registers Observer handlers for notifications it will emit.
*
* <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:
* // "Adding: 1"
* // "Adding: 2"
* // "Adding: 3"
* // "Sum equals: 6"
*
*
* @example <caption>Subscribe with functions</caption>
* let sum = 0;
*
* Rx.Observable.of(1, 2, 3)
* .subscribe(
* function(value) {
* console.log('Adding: ' + value);
* sum = sum + value;
* },
* undefined,
* function() {
* console.log('Sum equals: ' + sum);
* }
* );
*
* // Logs:
* // "Adding: 1"
* // "Adding: 2"
* // "Adding: 3"
* // "Sum equals: 6"
*
*
* @example <caption>Cancel a subscription</caption>
* const subscription = Rx.Observable.interval(1000).subscribe(
* num => console.log(num),
* undefined,
* () => console.log('completed!') // Will not be called, even
* ); // when cancelling subscription
*
*

* subscription.unsubscribe();
* console.log('unsubscribed!');

* 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!
