Backbone.js VS jQuery?

I was intrigue by this backbone.js, as far as I know it’s just a library just like jQuery.
But the BIG question is what’s the advantage over jQuery?

Anyone would like to explain.

Thank you very much in advanced.

I think this answered my question.

Okay I got it now.
So when I mastered jQuery, I should study backbone.js too and then angular.js.

What else that are JavaScript related and worth learning?

Thanks in advanced.

Backbone and jQuery are actually quite different and not interchangeable. jQuery is more aptly described as a library, whereas Backbone is an actual framework. jQuery has lots of useful functions for things like ajax, effects, events, DOM, and so forthe. Whereas Backbone provides an application architecture with things like MVC, routing, and history.
