// Implementation Summary // // 1. Enforce API surface and semantic compatibility with 1.9.x branch // 2. Improve the module's maintainability by reducing the storage // paths to a single mechanism. // 3. Use the same single mechanism to support "private" and "user" data. // 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData) // 5. Avoid exposing implementation details on user objects (eg. expando properties) // 6. Provide a clear path for implementation upgrade to WeakMap in 2014

// Register as a named AMD module, since jQuery can be concatenated with other // files that may use define, but not via a proper concatenation script that // understands anonymous AMD modules. A named AMD is safest and most robust // way to register. Lowercase jquery is used because AMD module names are // derived from file names, and jQuery is normally delivered in a lowercase // file name. Do this after creating the global so that if an AMD module wants // to call noConflict to hide this version of jQuery, it will work.

// Note that for maximum portability, libraries that are not jQuery should // declare themselves as anonymous modules, and avoid setting a global if an // AMD loader is present. jQuery is a special case.
