8. What is a CDN?

A CDN, or Content Delivery Network, is a geographically distributed network of servers that work together to deliver web content to users based on their location. The primary purpose of a CDN is to reduce latency and improve website performance by caching static content, such as images, CSS, JavaScript files, and more. When a user visits a website, the CDN delivers the content from the server nearest to them, minimizing the time required to retrieve the data.

2. The Importance of Web Performance

Web performance plays a significant role in user experience and can directly impact business success. Slow-loading websites not only frustrate users but also lead to higher bounce rates and lower conversion rates. Studies have shown that even a one-second delay in page load time can result in a significant decrease in customer satisfaction and conversion rates. Therefore, optimizing web performance should be a top priority for website owners.

4.1.2 Step 2: Configuring jsDelivr URLs

After creating a project, you will be provided with a unique URL to access your files hosted on jsDelivr. This URL will be used in your website’s code to load the files from the CDN.

4.1.3 Step 3: Adding Resources to jsDelivr

To add files to jsDelivr, you can either upload them manually or use automated tools, such as GitHub integration or npm packages. These resources will be stored on jsDelivr’s servers and made available for distribution.
