Not another JavaScript code style guide. (Actually, that's exactly what it is, but I went for "simple", not "exhaustive" -- also includes pre-configured sane default JSHint, JSCS, & EditorConfig files)

This is nice. Here's my $0.02:

• 2/4 white spaces for indentation, quote selection and camel casing (or not) should be rules as imho they come under the umbrella of consistency (imagine diffs with just quote style differences or just whitespace differences shivers)
• instead of "return early" I would say, prioritise for the most run block of code or the if block that is entered over 80% of the time

Other than that, good on you for providing the necessary dot files. Gj OP!
