I summary I don't have a favorite language, they all kinda suck and kinda don't. It all depends on what I need to use them for.
1) all the libraries are it takes advantage of are written in Java and this doesn't fit the closure style of coding at all.
2) the available tools just suck. Sorry, but without autocompletion the time it takes to write something balloons way, way too high.
I guess 2 would have been less of an issue 20 years ago -- back then most of the IDEs that we use today did exist -- but it is not 20 years ago. It is now.
