Does backbone.js really require underscore.js?

backbone.js, javascript-framework, jquery, underscore.js

Solution

Backbone relies heavily on the Underscore library. You cannot have a Backbone application without Underscore.

Problem

As i am new to backbonejs and underscorejs, I want to know core meaning of those. As my understanding underscorejs is just like as jQuery library, we are using those functions in backbonejs. We can't develop backbonejs applications without underscorejs. Am i right? If my understanding is wrong please clear on this with simple words/examples. Thanks in advance.
