JavaScript is a high-level, interpreted programming language that is used to create dynamic and interactive web pages. Developed by Brendan Eich at Netscape in 1995, JavaScript quickly gained popularity as a client-side scripting language for creating front-end web applications. JavaScript can also be used on the server-side, through platforms like Node.js, to create full-stack web applications. JavaScript is used to add interactivity to web pages, allowing developers to create effects like animations, form validation, and dropdown menus. It is a versatile language that can be used with a variety of frameworks and libraries, including jQuery, React, and Angular. With the rise of the web as a platform, JavaScript has become one of the most widely used programming languages in the world.
