Code Style

• Space indentation (2 spaces)
• Double-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
• Always use curly braces
• 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;
}
