Introduction

Making HTTP requests is a fundamental part of web development, allowing you to interact with APIs and retrieve data. In JavaScript, there are two primary methods to achieve this: the Fetch API and XMLHttpRequest. This guide explores both methods, their syntax, and use cases.

Making HTTP Requests

1. Using the Fetch API

The Fetch API provides a modern and cleaner way to make HTTP requests and handle responses. It returns a promise that resolves to the response of the request.

Syntax

Example

2. Using XMLHttpRequest

XMLHttpRequest is an older way to make HTTP requests in JavaScript. It provides more control over the request and can be useful in certain scenarios, but it is more complex than the Fetch API.

Conclusion

Both the Fetch API and XMLHttpRequest allow you to make HTTP requests in JavaScript, but the Fetch API is more modern, easier to use, and works with promises. Depending on your project's requirements, you can choose either method to interact with APIs and handle data effectively.
