My observation is that if you use Java mainly through large frameworks, you won't mind as much switching to JavaScript. When using large frameworks, most of your day is essentially spent doing what I think of as configuration work -- making things fit together, rather than actual programming. That's not a value judgement -- I'm just describing very different jobs. If you are a configuration programmer then it really doesn't matter much what language you use. In fact, the simple ergonomics of the tools for a given set of tasks may be more important than the language itself.
