JavaScript is a versatile and widely used programming language primarily employed in web development to add interactivity, functionality, and dynamic behavior to websites and web applications. JavaScript is executed by web browsers, allowing developers to create interactive features that respond to user actions.
JavaScript is commonly used for tasks such as form validation, DOM (Document Object Model) manipulation, asynchronous data fetching (AJAX), animations, and event handling. It plays a crucial role in creating modern, responsive, and user-friendly web experiences.
JavaScript is supported by all major web browsers, making it an essential technology in web development.
