-## TimerMixin
-
-We found out that the primary cause of fatals in apps created with React Native was due to timers firing after a component was unmounted. To solve this recurring issue, we introduced `TimerMixin`. If you include `TimerMixin`, then you can replace your calls to `setTimeout(fn, 500)` with `this.setTimeout(fn, 500)` (just prepend `this.`) and everything will be properly cleaned up for you when the component unmounts.

-```javascript
-var { TimerMixin } = React;
-
-var Component = React.createClass({
-  mixins: [TimerMixin],
-  componentDidMount: function() {
-    this.setTimeout(
-      () => { console.log('I do not leak!'); },
-      500
-    );
-  }
-});

-We highly recommend never using bare timers and always using this mixin, it will save you from a lot of hard to track down bugs.
