XMLHttpRequest

XMLHttpRequest is a web technology that allows a web page to send and receive data from a server without reloading the entire page. This enables smoother user experiences by loading only the necessary information, like new content or updates. For example, when you scroll through social media and new posts load automatically, XMLHttpRequest is likely at work. It communicates with the server in the background, making web applications more dynamic and interactive. Although the name includes "XML," it can handle various data formats, like JSON, making it versatile for modern web development.
