Ask HN: Which JavaScript framework is worth investing time in?

Focus on continuing to learn JS well. Try to make the time you spend carry it's own weight. Don't waste time learning JS frameworks just for the sake of learning JS frameworks. Instead, build something that you or someone else will use. Otherwise, learn JS well well enough so that you understand what the framework does and why it would help you. Then you can answer this question yourself.

Also, there is this post by the author of Sammi.js which the author probably answers this pretty well.

If you like to make ui widgets to knock your users out then jQuery is where it is. A host of tools come with the basic library but jQuery UI delivers the sort of capability you need to delight your users.

Listen I’ve learned JavaScript the wrong way and then the right way [by reading JavaSript: the good parts] and i say hands down - Angular.js --- even thought it's in it's "premature" stage it's simply AMAZING! [easy to learn to compared to Backbone.js or Can.js]

+1 for angular.js

First of all I would recommend that you go through code samples in to do mvc

Read or try out a few libraries so you can get a feel for them.

For fronted development I use knockout js. Their documentation is very good. The interactive tutorials offer a great way to learn the framework. The framework itself is not vast and you can get started pretty quickly.

Although it is a matter of preference among the devs but I like the declarative binding style of knockout. It felt natural to me.
