What is jQuery
Installing jQuery plugins to a website
There are two different ways to install jQuery to a website.
eg :- “scripts/ jquery-1.11.3.min.js”
Both Google and Microsoft provide this service, you just have to link their file of jQuery to your website.
This will be faster than the first method but for offline sites this will not work, that because you have to connect to internet to grab the jQuery file to the website. But the website is an online thing, so most people prefer in this way.
