Anyone tried backbone.js with jquery?

Hi, I’m just starting to learn about jquery, and even though it seems very powerful, I haven’t wrapped my head around how to structure “a javascript application”…

Someone showed me backbone.js for a simple and easy way to structure javascript applications, and at first glance it looks very neat.

However, as I’m basically still clueless about these things, I wondered if any of you veterans have seen it/tried it ? Or any other “framework” that is not too complicated that can help you structure your javascript code ?
