Understanding Components in Ember 2

Components are a vital part of an Ember application. They allow you to define your own, application-specific HTML tags and implement their behavior using JavaScript. As of Ember 2.x components will replace views and controllers (which have been deprecated) and are the recommended way to build an Ember application. Ember’s implementation of components adheres as closely to the W3C’s Web Components specification as possible. Once Custom Elements become widely available in browsers, it should be easily to migrate Ember components to the W3C standard and have them usable by other frameworks. If you’d like to find out more about why routable components are replacing controllers and views, then check out this short video by Ember core team members Yehuda Katz and Tom Dale.
