I'm not sure I really buy it, if you want to use the libraries/frameworks others are using that's easy, there's plenty of content out there that pushes you in the right direction. You can also take a punt on a framework/library that hasn't been maintained, or doesn't seem to have much interest, but that's your choice.

Before picking a library, one should do some research: take a look at the issue tracker, the mailing-list, open the source code, etc. It will give a good idea whether it's a good bet or not. I don't think this issue is specific to JavaScript.

Note that the author comes from Java. Developpers coming from dynamic languages will be much less annoyed by JavaScript vibrant ecosystem.
