Code Style

• Tab indentation
• Single-quotes
• Semicolon
• Strict mode
• No trailing whitespace
• Variables at the top of the scope
• Multiple variable statements
• Space after keywords and between arguments and operators
• Return early
• JSHint valid
• Consistency

Example:

'use strict';

function foo(bar, fum) {
    var i, l, ret;
    var hello = 'Hello';

    if (!bar) {
        return;
    }

    for (i = 0, l = bar.length; i < l; i++) {
        if (bar[i] === hello) {
            ret += fum(bar[i]);
        }
    }

    return ret;
}
