Think of it as the missing link between jQuery and Rails. Suppose you have a form tag,
The code that will look at the
data-remoteon this form tag and other such attributes used that Rails looks at, and submit this form through AJAX is handled by rails.js. It is like a connector between Rails and jQuery. The source is rather simple which you can read at https://github.com/rails/jquery-ujs/blob/master/src/rails.js
