I expect JSLint was whining about using multiple `var` statements.

Using a single var and putting each declaration on its line is not incompatible:

    var foo = 4,
        bar = 5,
        baz = 6,
        qux = 'quux;


That feels like a situation that could easily end up (copy pasting something, someone adding another var, ...) in an unexpected global variable declaration.

    var foo = 4,
        bar = 5,
        baz = 6,
        sprinkles = 'wee';
        qux = 'quux';
Making `qux` global.
