  <a href="http://ejohn.org/blog/ecmascript-5-strict-mode-json-and-more/">John Resig - ECMAScript 5 Strict Mode, JSON, and More</a>
  <blockquote>
    Strict Mode is a new feature in ECMAScript 5 that allows you to place a program, or a function, in a "strict" operating context. This strict context prevents certain actions from being taken and throws more exceptions.
  </blockquote>
  <blockquote>Strict mode helps out in a couple ways:
    <ul>
      <li>It catches some common coding bloopers, throwing exceptions.</li>
      <li>It prevents, or throws errors, when relatively "unsafe" actions are taken (such as gaining access to the global object).</li>
      <li>It disables features that are confusing or poorly thought out.</li>
