JavaScript is a versatile and widely used programming language that powers dynamic and interactive elements on web pages. It was initially designed to run in web browsers, allowing developers to manipulate HTML and CSS in real time. Today, JavaScript is a key component of modern web development, enabling features like animations, form validations, and asynchronous data fetching.

One of JavaScript’s main strengths is its ability to run directly in the browser without requiring additional software. It follows an event-driven, functional, and object-oriented programming approach, making it flexible for various applications. Additionally, JavaScript supports APIs for tasks like manipulating the DOM (Document Object Model), handling user input, and making network requests.
