hello,

i'm currently looking at a little 3rd-party javascript library and i see a lot of "sign-prefixed" variables in it:

function_call(+value);

i know, that you can swap the sign, if you prefix a variable with '-', but why to prefix something with a '+' -- it doesn't do anything to the value, no?

thanks in advance!
