JavaScript in web development is a scripting language that enables interactive and dynamic content on websites. It is primarily used to manipulate the Document Object Model (DOM), allowing developers to update page elements without needing to reload the entire page. JavaScript works alongside HTML and CSS to create responsive user interfaces and enhance user experience. Common uses include form validation, animation, event handling, and asynchronous requests through technologies like AJAX. Overall, JavaScript is essential for building modern, engaging web applications that respond to user actions in real time.
