Backbone.js and jQuery

Question

It is said that Backbone handles all the higher level abstractions, while jQuery or similar libraries work with the DOM, normalize events and so on..

Could someone pleas

Answer 1

I have never heard of people using backbone.js across multiple pages. It's almost always some kind of single page app.

The single page may have many different models, views, and states and can result in a full blown, powerful app.

If you already have server-side template/view rendering in java then backbone.js is NOT for you. To get the most out of backbone.js you must move or duplicate some of that code in the front end javascript.

If you don't want to do a single page app (this just means an app without page refreshes or changes, but the url can still change and can look like multi-pages to the user) then you can keep all of your MVC on the server and you have no need for backbone.

Edit:

What backbone does is move some of the MVC stuff normally handled on the server and move them to the client. For many people this means forgetting about the server and just writing your app as a single page javascript app. The server becomes just a source of JSON/REST data. If you're not prepared to do that, then backbone.js is not that useful.
