<h2>Angular 2 Demo: Zones</h2>
<p>This demo shows how code is executed <strong>inside</strong> Angular's zone to
ensure the framework is notified when an event has happened. It also demonstrates how
code can be executed <strong>outside</strong> Angular's zone, which causes the UI to
not update after every event tick.</p>
<p>Click the buttons below to see the code in action.</p>
