Interacting with jQuery

Now that we have a form, let’s hook it up and see what happens. To do that let’s start by using jQuery, that wonderful library that almost everyone on the Internet seems to love. To me there is no more powerful tool set in the JavaScript eco system than that of jQuery. Originally released in 2006 by John Resig,⁴ jQuery is now used on 49% of the top 10,000⁵ websites in the world and is currently one of the most popular JavaScript libraries available. jQuery is a JavaScript library that lets you write clean and concise code for manipulating the HTML DOM, executing AJAX requests, and handling events and simple animations. It does all this and is cross-platform, meaning it supports most major browsers and operating systems.
