JavaScript is a widely-used programming language that is primarily used for web development. It is a versatile and powerful language that allows developers to create interactive and dynamic content on websites, including animations, forms, and other user interfaces.
JavaScript is a client-side scripting language, which means that it runs directly in a web browser on the user’s device. It is also commonly used in server-side environments, such as with Node.js, to build back-end applications and APIs.
