What is jQuery?

jQuery is a lightweight Javascript library which is blazing fast and concise. This library was created by John Resig in 2006 and

jQuery has been designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax.

jQuery can be used to find a particular HTML element in the HTML document with a certain ID, class or attribute and later we can use jQuery to change one or more of attributes of the same element like color, visibility etc. jQuery can also be used to make a webpage interactive by responding to an event like a mouse click.

jQuery is free, open-source software which comes under the permissive MIT License. As of Apr 2021, jQuery is used by 77.8% of the top 10 million most popular websites.

jQuery has been developed with the following principles:

  • Separation of JavaScript and HTML, which encourages developers to completely separate JavaScript code from HTML markup.

  • Brevity and clarity promotes features like chainable functions and shorthand function names.

  • Eliminates of cross-browser incompatibilities, so developers does not need to worry about browser compatibility while writing code using jQuery library.

  • Extensibility, which means new events, elements, and methods can be easily added in jQuery library and then reused as a plugin.
