I'm not who you originally asked, but I share his sentiment that javascript is a nice language. I've used python for years, have a few open source applications with Java, and written several scripts for my own purposes in C. I've also explored C++, haskell, scheme, ruby, and MIPS assembly. Not a whole lot of PHP. So I use javascript for everything? Not even close. But I still like it.

In recent times I have delivered commercial products in PHP, Python, Ruby and LiveCode. In the past (way past more than 10 years) I used to work with VB, Delphi, REBOL and some Java. While I was coursing engineering, we learned scheme (its great!)
