The CDN in jQuery stands for Content Delivery Network. The main purpose of CDN is to include jQuery without actually having to download or keep it in the website's folder of our website. There are plenty of such jQuery CDNs available in the market today. For example, Cloudflare, jQuery's CDN, Google and Microsoft CDN, etc.
A CDN is nothing but delivery or a distribution network, be it a geographically distributed network of proxy servers and its data centers. The main of CDN is to provide highly scalable performance and availability of relative service distribution to end-users. Let's discover some popular ways of exploring jQuery CDN by working with different types of options available these days. Before proceeding to make use of jQuery CDN, let's carry out the local installation to properly use it on our system.
Generally, there are two downloadable versions available for jQuery on the web. They are:
Production version: It is a compressed and minified version for your live website.
Developer version: It is primarily used for full fledged actions like developing and testing of readable and compressed code.
Note: It is recommended to use uncompressed version while programming or debugging and compressed versions for tasks like bandwidth and performance boosting.
The next task is to setup using the steps shown below.
After setting up jQuery into your HTML file, proceed by including the below code.
Now, you can make use of the jQuery CDN as shown in the below steps.
You can include the jQuery library directly into your index.html code from the CDN. If we talk about Google, consider the below HTML code for importing jQuery CDN into your HTML code.

The disadvantages of using jQuery CDN are as follows:
In this tutorial, we came across learning from scratch about how to set up jQuery to be used with CDN and not from your regular website. We also came across the overall architecture of the Content Delivery Network and how it enhances the performance of loading. We might have been familiar with HTML and CSS and alongside jQuery, CDN will help them enhance the load balancing factor to serve speed efficiently rather than depending upon the website. We also came across various installation techniques be it Google, Microsoft, or Cloudflare, and how to include them in the <head> tag of our HTML file. Lastly, we came across the advantages and disadvantages of using jQuery and discussed on what basis it should be used and when it should be implemented.
The jQuery CDN is therefore a unique toolkit for providing valuable load balancing support alongside managing the relative delivery service to the end-users.
