Installing jQuery

0 779

  • There is no installation required to use jQuery.
  • We just need to place it on our site in a directory.
  • Since JavaScript is an interpreted language, there is no worry about the compilation or build phase.
  • Whenever we need a page to have jQuery available, we will simply refer to the file's location from the HTML document.

How to install jQuery

We can install jQuery in our application in two ways:

  • By downloading: The official jQuery website (https://jquery.com/) is always the most up-to-date resource for code and news related to the library.
  • By using CDN: CDN stands for Content delivery network. We can include jQuery from CDN directly without downloading any source code.
