👉 JavaScript is a high-level, dynamic programming language that runs on web browsers and Node.js environments, enabling interactive and dynamic web content. It operates on the Document Object Model (DOM), allowing developers to manipulate and interact with web page elements directly in the browser. JavaScript uses a syntax that is both readable and concise, with features like functions, loops, conditionals, and object-oriented programming to handle complex logic. It supports asynchronous operations through Promises and async/await, making it suitable for handling tasks like network requests and timers. JavaScript's vast ecosystem of libraries and frameworks, such as React, Angular, and Vue.js, further enhances its capabilities for building sophisticated web applications and services.
