About Programming Language - JavaScript


JavaScript is a versatile, high-level programming language primarily used in web development. It runs in web browsers and enables dynamic, interactive features on websites, such as animations, form validation, and real-time updates. 

JavaScript has become a cornerstone of modern web development, powering web applications' front-end and back-end through technologies like Node.js. Its flexibility and ubiquity make it a fundamental language for building web-based solutions and a key tool in the developer's toolkit.
