Fetch
Fetch is a modern way for websites to communicate with servers and get information from them. It's like a messenger service that helps web pages request and receive data without needing to reload the entire page. For example, when you're on a social media site and new posts appear without refreshing the page, that's often using Fetch. It's the newer, more efficient replacement for older methods like XMLHttpRequest (XHR). When you see Fetch mentioned in a resume, it usually means the person knows how to make websites that update smoothly and provide a better user experience.
