JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user.

JavaScript is a powerful scripting language used to make web pages interactive and dynamic. It allows developers to add features like animations, interactive forms, real-time updates, and multimedia controls. Unlike static HTML, JavaScript lets websites respond to user actions — for example, validating input, displaying notifications, or loading new data without refreshing the page. It’s also widely used in web and app development, from building front-end interfaces with frameworks like React to powering back-end servers with Node.js.
