JQuery is quite possibly the most popular JavaScript library out there, and provides a bunch of features still super useful for present day development. It is a lightweight JavaScript library, and its creator has given it the slogan of "write less, do more". The purpose of jQuery is to make it much easier to use JavaScript on websites. The library takes a lot of common tasks that used to require multiple lines of JavaScript code to accomplish, and wraps them into methods that you can easily call with a single line of code.

There are a couple of important steps that need to be taken in order to use jQuery on your website. The first step to take is to actually download the library and link your HTML page to it in a source tag. That should look a little similar to this.

Another thing that has to be done before you can start using jQuery is calling a document.ready function. All of your code will go inside of the function body. This will ensure that everything on the DOM is fully loaded before any jQuery methods will be invoked, since you wouldn't want to manipulate an element before it even loads on the page.

  $(document).ready(function() {

      // All your jQuery will go here!

  });
