The Fetch API offers a streamlined JavaScript interface for HTTP requests using the fetch() method, which returns a promise resolved with a Response object. It enables data retrieval, POST requests, error handling, and streaming for large datasets. The API uses headers for request and response metadata management. Fetch provides a more modern approach to network requests in web applications compared to older methods like XMLHttpRequest.
