Because WordPress and jQuery are anticipating other libraries to be loaded which may use the short variable,
wp_enqueue_script ensures jQuery is loaded up in
noConflict mode. Therefore, you'll also need to make sure to write your custom jQuery code in
noConflict mode's syntax. The easiest way to do this is to replace the
$ variable (common in many jQuery scripts) with the full
jQuery variable, as I've discussed in Chapter 1, Getting Started: WordPress and jQuery, and done in my two previous samples.
