I've been thinking about choosing a javascript framework for a few weeks now, and, having no experience using any, so I was hoping for suggestions.
Frameworks on my radar are Prototype, Dojo, Scriptaculous, MochiKit, and I've briefly hit up the frameworks page on the Ajax Patterns wiki, but have become pretty completely overwhelmed.
Does anyone actually use OSS JS Frameworks? For all of my projects, so far, I have always built my own from scratch, but I'd love to build on the work that a lot of others have already put in.
