JQuery came out of nowhere one day and became a controlling force on the internet. If you do not know what it is, we will give you the simple form. JQuery is a “library” of useful code pieces that can be used to do all manner of things on a website. You simply make a “call” to the library at the top of the page and then many things that would take line after line of code can be accomplished with just a line or two.
Imagine if you could walk in the kitchen and simply say “Make some pancakes” instead of going through all the steps or “Change the oil” and have it done. That is the magic of a good code library and JQuery has filled the bill. The problem with using a library on a site that has many pages is that you either have to include the plugin link in every page or in a page that is loaded every time the site is loaded. In this day and age jQuery has become so widely used that many other plugins depend upon it. When installing another plugin it may or may not mention the fact that you do not have jQuery installed and the next step is up to the developer. Some will ask you to update jQuery and others will install the framework of their choice. If you want control over your site and your blog, then choose the jQuery plugin that you want.
