jQuery is a feature-rich, quick, and lightweight JavaScript library built on the concept of "write less, do more." Its straightforward APIs make tasks like HTML document crawling and modification, event handling, and adding animation effects to a web page much easier, and it works across all major browsers such as Chrome, Firefox, Safari, Internet Explorer, and others.

jQuery also allows you to quickly and easily develop an Ajax-based application. jQuery is used by big corporations like Google, Microsoft, and IBM in their applications. So now you have a good idea of how popular and strong jQuery is.

In early 2006, John Resig created jQuery for the first time. As an open-source project, the jQuery project is currently administered and maintained by a scattered group of developers.

What jQuery Can Do for You

There's so much more you can do with jQuery.

• You can easily manipulate items by selecting them.
• You can quickly construct effects such as showing or hiding components, sliding transitions, and so forth.
• With less lines of code, you can simply build complicated CSS animation.
• DOM elements and their attributes are simple to alter.
• Ajax can be used to facilitate asynchronous data transmission between the client and the server.
• To find any element in the DOM tree, you can quickly go all the way around it.
• With a single line of code, you can simply perform several actions on an element.

This jQuery tutorial series covers all of jQuery's features, including as its selector mechanism, event handling system, and effect techniques for creating interactive user interface features such as showing and concealing components, animating elements on a web page, and so on.

Later on, you'll learn how to use jQuery to perform common DOM manipulation tasks like getting or setting the contents and values of an HTML element on a web page, adding or removing elements or their attributes, getting and setting CSS properties of an element, getting or setting the width and height of an element, and so on.

Finally, you'll learn about one of jQuery's most powerful features: traversing the DOM tree to retrieve child, parent, and sibling elements, as well as filtering element selection, using Ajax to retrieve data from a server and update the page content without refreshing it, and avoiding conflicts between jQuery and other JavaScript libraries.
