But often overlooked are the metrics tracking the size, strength, and momentum of the communities and ecosystems surrounding these open source projects.
These stats should play a key role in your selection. [ How much do you know about this stalwart developer tool? Earlier this year, I had the opportunity to do an analysis of the fastest-growing open source projects started in 2012, and I was struck by the number of JavaScript projects on the list. Project contributors per month: The number of contributors to Ember took off like a rocket when the project was forked from SproutCore in December 2011. A comparison of Angular, Backbone, CanJS and Ember - Sebastian's Blog. Selecting a JavaScript MVC framework can be hard work. There are so many factors to consider and so many options out there that selecting a framework can be overwhelming.

So I decided to create a comparison to help you decide which one to use. I will go through several factors that you might want to consider when choosing one. To each factor I have assigned a score between 1 and 5. Features There are really important features a framework should have to provide the necessary foundation to build useful applications. Observables: Objects that can be observed for changes. Routing: Pushing changes to the browser url hash and listening for changes to act accordingly. View bindings: Using observable objects in views, having the views automatically refresh when the observable object change.
