jQuery is a very powerful, fast, small and a rich JavaScript library. When we say jQuery as powerful and rich, we mean that it does things like DOM manipulation, event handling, animation and Ajax under a single JavaScript library. Ajax is a much simpler and easy-to-use API that works across browsers. It was originally written by John Resig and it was influenced by Dean Edwards cssQuery library. It is currently maintained by a team of developers which is led by Timmy Willison.

Generally, the question that arises is ‘Why jQuery?’ when there are a lot other JavaScript frameworks out there. The answer to ‘why jQuery?’ is that jQuery a lot more extendable than other libraries. Also, it provides cross-browser support where it runs exactly the same in all major browsers, including the support to Internet Explorer 6! And this is not the only reason. There are several other reasons for using jQuery. Some of them are listed below: –

  • It is a lightweight JavaScript library supporting multiple features.

This is the reason why page loads faster. Being a lightweight library and supporting thousands of features including CSS manipulation, DOM manipulation, Ajax, animation and a lot more.

  • It is Open Source.

  • Easy DOM traversing and manipulation
