Introduction to jQuery

  • jQuery was released in 2006 by John Resig.
  • It has a nice motto of “Write less – do more”.
  • It has an open-source, cross – browser library.

Features of jQuery

The library consists of the following features:

DOM Manipulation
jQuery has made it easy to select the DOM elements, traverse them and modify the content by using the cross-browser open source selector engine called Sizzle.

Event handling
It captures a wide variety of events such as user clicking on a link, without the need to clutter the HTML code itself with the event handlers.

AJAX Support
It helps in developing a responsive and feature-rich site by using the AJAX technology.

Animations
It has plenty of built-in animation effects which can be used for the websites.

Lightweight
It has a lightweight library which is about 19KB in size.
