 Intro to jQuery, one of the most popular JavaScript libraries

• About:
  • jQuery  is one of the most popular JavaScript libraries because it’s easy to use for adding animations and other interactive elements. More than half of websites use jQuery!
  • jQuery is a JavaScript library and you should have a basic understanding of JavaScript to use it.
  • Unlike JavaScript, jQuery is NOT built into the browser automatically, so, like other libraries, you need to download it and add it to your webpage by linking to it OR you can use a CDN (content delivery network)  (we will do this)
  • Everything you need to use jQuery is on jQuery.com 
• Practice: We are going to start practice writing some jQuery right away with these mini-tutorials.
