Valid Characters for JavaScript Variable Names

Started learning Javascript and found out that one can name a variable like

var $importantVar;

I am wondering can we name variables with a $ sign while all other special characters are not allowed?

Note: I know you can use _ too before the name but thats something which is allowed in all other languages too(At least C and C++).

You can name it `_importantVar` too. – Waleed Khan Jan 18 '13 at 17:34

You can also use the underscore `var _` – David G Jan 18 '13 at 17:34
