   * <p>The JSON module adds support for serializing JavaScript objects into
   * JSON strings and parsing JavaScript objects from strings in JSON format.</p>
   *
   * <p>The JSON namespace is added to your YUI instance including static methods
   * Y.JSON.parse(..) and Y.JSON.stringify(..).</p>
   *
   * <p>The functionality and method signatures follow the ECMAScript 5
   * specification.  In browsers with native JSON support, the native
   * implementation is used.</p>
   *
   * <p>The <code>json</code> module is a rollup of <code>json-parse</code> and
   * <code>json-stringify</code>.</p>
   *
   * <p>As their names suggest, <code>json-parse</code> adds support for parsing
   * JSON data (Y.JSON.parse) and <code>json-stringify</code> for serializing
   * JavaScript data into JSON strings (Y.JSON.stringify).  You may choose to
   * include either of the submodules individually if you don't need the
   * complementary functionality, or include the rollup for both.</p>
