I guess the 3-4 copies of jQuery are my point; that&#x27;s generally indicative of a misunderstanding of how things work.<p>Taking my own learning as an example, I want to build a single-page application, so I decided that I needed a framework to manage it, since that&#x27;s what all the cool kids were doing. While sipping on a frosty beverage, I was comparing Backbone and Angular, and then realized that Parse (which I&#x27;d already decided to use) built their JS API on top of backbone. That quickly simplified things for me, but I still see people that are trying to bolt together angular and parse.
