JavaScript

JavaScript is a programming language created in 1995 by Brendan Eich and standardized in 1997 by the TC39 committee of ECMA International. It is designed as a prototype-based object-oriented language, featuring dynamic typing and functional programming capabilities. Originally introduced as a scripting language to add simple interactivity to web pages, JavaScript has since evolved into a versatile, general-purpose programming language used across multiple environments. JavaScript is supported by built-in engines in all major web browsers and, along with HTML and CSS, forms one of the core technologies of the web. While HTML defines the structure and CSS handles the presentation, JavaScript is responsible for enabling dynamic behavior, responding to user input, and updating content in real time. Using a car analogy, HTML can be seen as the frame, CSS as the exterior design, and JavaScript as the engine that powers movement. Today, JavaScript extends far beyond the browser. With technologies like Node.js, it is widely used in server-side development, as well as in mobile and desktop applications. Modern frameworks and libraries such as React, Vue, and Angular enable developers to build complex and scalable user interfaces efficiently. With its asynchronous capabilities, event-driven architecture, and vast ecosystem, JavaScript has become a core technology that enables full-stack development across both frontend and backend environments.
