Javascript vs. AJAX: Know the Difference
By Shumaila Saeed || Published on February 8, 2024
JavaScript is a programming language for web development, while AJAX (Asynchronous JavaScript and XML) is a technique using JavaScript for asynchronous web requests.
Key Differences
JavaScript is a versatile scripting language used to create interactive elements on websites, functioning in various environments like browsers and servers. AJAX, a subset of JavaScript functionality, specifically refers to a method of exchanging data with a server and updating parts of a web page without reloading the entire page.

JavaScript can manipulate HTML and CSS, creating dynamic content and enhancing user experience on web pages. AJAX, as a technique in JavaScript, allows web applications to send and retrieve data from a server asynchronously, meaning the page doesn't need to be reloaded for data update.

JavaScript enables developers to implement complex features on web pages, from animations to user interface control. AJAX, while utilizing JavaScript, focuses on minimizing interruptions in user experience by sending data to and receiving data from a server in the background, without affecting the display and behavior of the existing page.
