I feel this way about backend frameworks, but to me if you take the time to learn something like Angular, it saves will reduce the bulk of the code substantially, compared to using jQuery for example. A listener for this, a listener for that? No, just data-bind and be done with it. There are challenges of course. Once you are in, you are all in, and you will be maintaining this application for its lifetime or rewriting it. Javascript frameworks these days move at the speed of sound, so if you start writing it today at while your framework is at v1.0, there is a good chance that your framework will be v1.5 by the time you release, with several breaking changes. This is probably the most aggravating part to me. I have thought that perhaps the diversity of opinions on these sorts of issues, and the speed at which these frameworks are written and rewritten are symptoms of a larger problem, namely the browser as a platform.
