JavaScript
« Back to Glossary IndexJavaScript is a high-level programming language used to add interactivity and dynamic behavior to web pages. It enables developers to manipulate HTML and CSS in real time, respond to user actions such as clicks and input, and update content without reloading the page.
JavaScript runs in the browser’s execution environment and can interact with the Document Object Model (DOM), allowing it to modify page structure, handle events, and communicate with servers via APIs. It is a core web technology alongside HTML and CSS, forming the foundation of modern interactive web applications.
