I've been using JS lightly for a couple of years, in earnest for a couple of months. From the perspective of someone who's comfortable in C, Lisp, Python I think the semantics are fine (given a certain subset). One major issue I have with JS is that the standard library is severely lacking in the basics. We have Promises but Math.round only rounds to the nearest integer. We have generators but no string formatting (the template syntax is not a replacement).
