jQuery is a great framework that make our life easer when it comes to start writing javascript or manipulate the DOM.

The only problem is that because jQuery make everything easer some developer forget to write good jQuery, that is following almost the same good practices that developers should use when writing JavaScript.

A very simple example of this is the following:

$(“document”).ready(function() {

});

This is the most popular way to start using jQuery. If you don’t care about populating with globals variables or the loading performance is not a worry for you, this kind of code works for you.

But when you are working with bigger applications you don’t want that your variables gets globals and obviously you want the best performance for you app.

The solution is follow the best practices. The example above can be written like this:

(function($, window, document) {

// now $ is locally scoped

$(function() {

// the DOM is ready

});

}(window.jQuery, window, document));
