Overview of JavaScript

JavaScript is a versatile programming language commonly used for creating dynamic and interactive content on web pages. It is one of the core technologies of the World Wide Web, alongside HTML and CSS. JavaScript enables client-side scripting, which allows developers to implement features such as interactive forms, real-time updates, and animations. Initially designed for web browsers, JavaScript has evolved to support server-side development with environments like Node.js. Its flexibility and widespread adoption make it an essential tool for modern web development.
