The Fetch API is a modern web API that provides a more powerful and flexible feature set for making HTTP requests and handling responses than the older XMLHttpRequest. It is promise-based, allowing for cleaner and more readable asynchronous code, and supports a wide range of features such as streaming requests and responses, handling CORS, and working with different types of data formats.

HTTP requests are the foundational mechanism by which clients and servers communicate over the web, enabling the transfer of data and resources between them. They consist of a request line, headers, and an optional body, which together specify the action to be performed and the data to be processed.

XMLHttpRequest is a JavaScript API that enables web pages to make asynchronous HTTP requests to servers, allowing for dynamic content updates without reloading the entire page. It is a core component of AJAX and has been largely supplanted by the Fetch API in modern web development due to its more intuitive syntax and promise-based structure.

Asynchronous code lets a computer do many things at the same time, like playing a game while also listening to music. It helps the computer not get stuck waiting for one thing to finish before starting another.

Data formats are structured ways of organizing and storing data to ensure its accessibility and usability across different systems and applications. They are crucial for data interchange, compatibility, and preservation, influencing how data is processed, analyzed, and shared in digital environments.
