How to add jQuery from a CDN?
A content delivery network or content distribution network (CDN) is a network of proxy servers globally distributed throughout multiple locations where users can access cached content. It hosts resources such as images, and other CSS and javascript files.
The core purpose of CDN is to virtually shorten the physical distance between the end-users and the hosting-servers of the website the user wants to access. This results in improved content rendering time and website performance.
jQuery CDN
jQuery is a feature-rich JavaScript library which makes using JavaScript on your website easier.
It will take time to download jQuery library form your server and increases latency but if you don’t want to host jQuery yourself, then the best approach is to include it from CDN. Just include the script in your code and you are good to go.
Let’s look at the illustration for better understanding:
There are two ways of including jQuery, either from google or Microsoft.
Google CDN
<head><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script></head>
Microsoft CDN
<head><script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.3.1.min.js"></script></head>
