    I’m going to show you how to do what you want, and then tell you what I think about it:

    (function checkJquery() {
  if (typeof(jQuery) == 'undefined') {
    setTimeout(checkJquery, 500);
  }
  else {
    alert('jQuery is loaded.');
  }
})();

    Normally when you’re using jQuery, you would will include it in a <script> tag in your <head>. All such scripts are loaded in the order they are defined, so if you load it first, it will be available for all subsequent scripts. Therefore you should never need to check for it.

    If you find yourself using a lot of javascript functionalities on your site, and want to make sure all your module dependencies are in check, I would suggest to check out RequireJS
