JavaScript is a versatile and widely used programming language that plays a fundamental role in web development. It was created to make web pages more interactive by allowing developers to add dynamic behavior and interactivity to websites
JavaScript is primarily a client-side scripting language, which means it runs in the web browser of the user. This enables it to manipulate and interact with the Document Object Model (DOM) of web pages, allowing for real-time updates and user interactions without requiring communication with the web server.
