// 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. For more information, see

// https://github.com/jrburke/requirejs/wiki/Updating-existing-libraries#wiki-anon
