Which characters can be used for naming a JavaScript variable?
I want to create a small "extension library" for my non-JavaScript users here at work (who all seem to be squeamish when it comes to the language). I love how jQuery and Prototype have both use the $ dollar sign, and since I use jQuery, I'm looking for another nice single-character symbol to use.
I realize that I could just test out a number of characters, but I'm hoping to narrow down my list of characters to start with (in consideration of future integration with another popular library, perhaps).
