The Awesome Scripting Universe

I read a nice survey (sponsored by Microsoft?) of scripting languages. However, I find it rather odd, briller par son absence, that two popular languages—JavaScript and Visual Basic—are not covered. Five illuminati of the open-source literati each give eye-popping demonstrations of what's possible (in Tcl, Perl, Python, PHP, and Ruby respectively). Inspired, I'm going to study the RAD capabilities of Perl and Python.
