Steve Yeggae's js2-mode highlights globals during editing, and it's saved me a good many times.

Mind you it won't catch globals declared in chained assignments

eg

    var x = y = 0; // y is defined globally

The fork of js2-mode at https://github.com/mooz/js2-mode will catch that, as will js3-mode.

If you're looking for a new IDE, JetBrains WebStorm does this. In the chained assignment, as well.
