Example 2: what is jquery
jQuery is a lightweight, "write less, do more", JavaScript library.
The purpose of jQuery is to make it much easier to use JavaScript on
your website.
jQuery takes a lot of common tasks that require many lines of JavaScript code
to accomplish, and wraps them into methods that you can call with a single
line of code.
