JavaScript is a high-level, dynamic, and interpreted programming language that is primarily used for adding interactivity and functionality to websites. It is a core technology of the World Wide Web, alongside HTML and CSS. JavaScript enables developers to create interactive effects within web browsers, such as responding to user inputs, manipulating the Document Object Model (DOM), and communicating with servers through AJAX (Asynchronous JavaScript and XML).
JavaScript is event-driven, meaning it can respond to user actions like clicks, key presses, and mouse movements. It is also versatile, as it can be executed on the client side (in a web browser) and, more recently, on the server side (e.g., using Node.js). JavaScript supports multiple programming paradigms, including object-oriented, functional, and imperative programming.
Due to its ubiquity and support by all major web browsers, JavaScript has become a foundational technology for modern web development, powering a vast array of web applications and services. Its extensive ecosystem includes frameworks and libraries such as React, Angular, and Vue.js, which facilitate complex application development.
With an increasing emphasis on interactive web experiences, JavaScript remains a crucial tool for developers. Many online platforms continue to rely heavily on this programming language to enhance user engagement…
