JavaScript
JavaScript (often abbreviated as JS) is a high-level, interpreted programming language primarily used for creating interactive and dynamic content on the World Wide Web. It is one of the core technologies of web development, alongside HTML and CSS, enabling client-side scripting to manipulate web page content, respond to user actions, and communicate with servers. JavaScript is a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.
