Re: [jslint] JSLint doesn't check if global variables are used.

The only possible purpose of declaring a global variable/function/object/whatever is so that it can be accessed globally â" from everywhere, and in particular, from elsewhere. I find the current behavior of JSLint (not forcing me to declare globals twice for clarity) to be correct. Declaring a global in some file and not using it in that file (but possibly in every other file loaded) should not result in errors or warnings.
Although it would be great to have this same helpful hint with global variables, it's been shown in this thread that such a system would almost certainly be needlessly complex, without very much gain.
