can work on <em>all</em> browsers. This means you can write modern JavaScript and use

  <p><em>Note: Some features require you to <a href="https://github.com/babel/ember-cli-babel#polyfill">enable the Babel polyfill</a>.
This adds some extra weight to your application, but ensures you'll be
compatible with any new features that are added to JavaScript.</em><
