Implements Zones for JavaScript, inspired by Dart.

If you're using zone.js via unpkg please provide a query param ?main=browser
https://unpkg.com/zone.js?main=browser
If you're using the following library, make sure you import them first

• 'newrelic' as it patches global.Promise before zone.js does
• 'async-listener' as it patches global.setTimeout, global.setInterval before zone.js does
• 'continuation-local-storage' as it uses async-listener

See the new API here.

Read up on Zone Primer.

A Zone is an execution context that persists across async tasks. You can think of it as thread-local storage for JavaScript VMs.

See this video from ng-conf 2014 for a detailed explanation:

• async-listener - a similar library for node
• Async stack traces in Chrome
• strongloop/zone
• vizone - control flow visualizer that uses zone.js

zone.js patched most standard web APIs(such as DOM events, XMLHttpRequest...) and nodejs APIs (EventEmitter,fs ...), for more details, please see STANDARD-APIS.md for more details.

And now we are adding support to some non standard APIs, such as MediaQuery, Notification. Please see NON-STANDARD-APIS.md for more details.
