What is jQuery?
jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps. Often with jQuery you can write a single line of code to achieve what would have taken 10-20 lines of regular JavaScript code.
jQuery is itself written in JavaScript, and comes in the form of a single
.js file that you link to from your webpage. Your JavaScript code then accesses the library by calling various jQuery functions.jQuery is great library for developing ajax based application. jQuery is great library for the all type web programmers (developing web related applications), which simplifies the development of web 2.0 applications. You can use jQuery to develop cool web 2.0 applications. jQuery helps the programmers to keep code simple and concise. The jQuery library is designed to keep the things very simple and reusable.
jQuery library simplifies the process of traversal of HTML DOM tree. You can use jQuery to handle events, perform animation, and add the ajax support into your web applications with ease.
Why jQuery?
You can use simple JavaScript to perform all the functions that jQuery provides. Then why jQuery? The jQuery library is providing many easy to use functions and methods to make rich applications.

You can use jQuery in all the web based applications irrespective of the technology.
jQuery is java script and can be used with ASP.NET, ASP, PHP, JSP, Servlets, CGI and almost all the web programming languages.
The jQuery code is very simple and easy to learn.
What you can do with jQuery?
jQuery makes it easy to write powerful JavaScript apps and create eye-catching animated effects rivalling those of Flash movies. Amongst other things, jQuery is great for:
- Adding animated effects to elements. jQuery lets you easily add effects such as fading in/out, sliding in/out, and expanding/contracting.
- Making XML (Ajax) requests. These use JavaScript to request additional data from the Web server without having to reload the page.
- Manipulating the DOM. You can easily add, remove, and reorder content in the Web page using just a couple of lines of code.
- Creating image slideshows. You can use jQuery effects to build nice animated slideshows and lightboxes.
- Making drop-down menus. jQuery makes it easy to create multi-level dropdowns with animations.
- Creating drag-and-drop interfaces. Use jQuery to build a page with elements that can be repositioned or reordered simply by dragging and dropping.
- Adding power to forms. With jQuery you can easily add complex client-side form validation, create auto-complete Ajax text fields that pull data from a server-side database, and so on.

How much time is required to learn jQuery?
You can learn jQuery in a day and master it within 2-3 days. There are so many features available with jQuery and you may spend months to explore these features.
We have spent huge time in exploring the jQuery and developing almost all the examples that can be developed with jQuery. So, explore our huge collection of jQuery tutorials and examples. Please continue reading the tutorials.
How compatible with different browser?
Another of jQuery's strong points is that it makes it easy to write JavaScript that works on many different browsers. Incompatibilities between popular browsers such as IE, Firefox and Safari mean that you often need to write different chunks of JavaScript code for each browser. With jQuery, however, you just call the appropriate jQuery function and let jQuery deal with making the code run on different browsers. Is that not great?
