JavaScript HTTP Requests 101: Everything You Need to Know
Reading Time: 3 minsHTTP requests are a fundamental part of web development, allowing you to send and receive data from servers and APIs. In JavaScript, you can use the XMLHttpRequest object or the newer fetch() API to make HTTP requests. Both of these methods allow you to specify the type of request (e.g. GET, POST), the URL of the resource you want to retrieve, and any data you want to send in the request body. To handle the response from the server, you can use the onload event of the XMLHttpRequest object or chain a then() method to the Promise returned by the fetch() function. In this article, we’ll take a comprehensive look at how to make HTTP requests in JavaScript using both the XMLHttpRequest object and the fetch() API.
