jQuery is a common JavaScript library for reading and making changes to the
Document Object Model (DOM). The DOM is a tree structure that contains information
about what is shown on a webpage.
We all know that HTML is a static document. JavaScript’s functionality comes from its ability to manipulate the DOM, which is basically a JavaScript
object. jQuery is fast and easy to use, but it doesn’t do anything you can’t accomplish with basic JavaScript.
jQuery is the most popular of JavaScript libraries out there.
