I'm working on a little programming language myself that compiles to Javascript. In most languages that do this, I wish there was better information on the mapping between the domain language and its Javascript codomain. I think this would be a good open source project idea: a tool to assist in the compilation of various languages to Javascript. Something to the effect of how source lines in C can be printed above their generated assembly. Anyone want to give it a shot?
implementing a vm in javascript would be noticeably slower than compiling directly to javascript. Dart has its own vm, which will eventually be bundled with chrome since it's a google-backed project, but for backwards compatibility it still needs a dart source to javascript source compiler.
