Ember.js is a leading client-side framework — letting you create rich, desktop-style applications that run within the browser, and which communicate easily with a server. In this talk, Yehuda Katz describes what the Ember.js developers have aimed to do, and their process for doing so. How have they released new versions without breaking previous code? How have they tried to learn from other frameworks? This talk shows how Ember.js has tried to do all of these, and more, as they build a solid framework that is growing in popularity.
