We are using Ember.js for our upcoming release of billysbilling.com. It's a huge app. We already have 60 different routes and several hundred .js files.

The best thing about Ember that I always tell curious newcomers is that Ember is both easy to make small apps with, but it's also trivial to keep expanding into really big apps. You can keep repeating the same pattern infinitely without rewriting old parts of the app, and without feeling like adding bulk to the app. I see our app as a large very flat structure. We can go in and replace every small piece in isolation to everything else.

My impression of something like Angular.js is that often when you want to add new features you have to go back and refactor a lot of stuff (just check out the cage match between Tom Dale and Rob Connery https://vimeo.com/68215606). It feels like a pyramid that will need a lot of maintenance to stay standing.

This is not the case with Ember. Ember was written by some very smart people, who have spent _a lot_ of time refining how an app should be developed in the long run. Features are prepared for the future. Both the future of browsers and JavaScript but also the future of developers' apps.

I am sure that Ember will prevail over all the other frameworks within the next year and stay on top for many years to come.
