There seems to be a javascript toolkit with ruby-style syntax ...

Out of the sandbox ?

Few people know that on windows, if you rename .html to .hta, then 
javascript will gain the ability of accessing filesystem, spawning 
process, even calling DirectX. So you can write fully-featured gui 
programs in javascript with notepad, without install anything else ...

Another popular javascript tool is Rhino, which is cross-platform.
