What is Fetch API?

The Fetch API is a modern replacement for the XHR object in AJAX. It provides a cleaner and more powerful way to make HTTP requests and handle responses in JavaScript. Fetch is promise-based, which makes handling asynchronous requests more intuitive compared to the callback-heavy XHR.

Key Features of Fetch API:

  1. Simpler syntax compared to XHR.
  2. Supports Promises for better error handling and chaining.
  3. Allows customization of requests (headers, methods, body, etc.).
  4. Provides support for various data formats, such as JSON, text, blobs, and streams.
