True or false? Pre-fetch and pre-render are especially useful when you do not depend on 3rd party requests or contents from a CDN or a subdomain.

The statement is false. Pre-fetch and pre-render are more useful when you do depend on third-party requests or content from a CDN or subdomain. These techniques aim to improve user experience by loading resources in advance. Pre-fetch downloads resources that might be needed later, while pre-render loads an entire page in the background. When content comes from external sources like CDNs or subdomains, there's often additional network latency involved. By pre-fetching or pre-rendering these external resources, you can mitigate the impact of this latency, making the page load faster for the user. If a site had no external dependencies, the benefits would be less pronounced as all resources would be local and potentially already optimized.
