jQuery is lightweight, client side script JavaScript library file that supports all browsers.Query is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery makes it easy to play with the DOM, add effects, and execute Ajax requests.
This helps developer to reduce lines of code while he program. For example huge code written in Java Script, can be done easily with JQuery in one or two lines as it uses pre compiled JavaScript library internally. For example To find a Div that have class xxx we can do this using custom JavaScript by looping through all DOM elements, Find Div element write if statement checking the class then write the code to manipulate cross browser. But this can be achieved using jQuery with 2 lines of code. jQuery is a fun library to use and play.
