Possible Duplicate: Why would a JavaScript variable start with a dollar sign? I realized some syntax with jquery and didnt know what it is. here goes: var $foo = $("bar").blah(); var hello$ = $("stgelse").etc(); What is the difference between these? and why are they like that? Also, For example: var $foo = $("").blah(); var should already contain whatever right side is returning ? no? Can you please elaborate?
