> It lacks a first-rate IDE

That is an interesting claim. What are the first rate IDEs for Javascript, Python, Ruby or C++? That isn't a rhetorical question I mean vim, emacs, textmate all seem equally good for Javascript and Lua. I know people use Eclipse for Javascript but it hardly seems like a killer integration.

Something like Xcode, Codeblocks, MS Visual Studio, Eclipse, Komodo, or Python IDLE.

Ruby: RubyMine Javascript: integration in IntelliJ IDEA was always very good

There's also WebStorm which is the JavaScript/HTML/CSS specific IDE from Jetbrains.
