JavaScript (JS) is a high-level, cross-platform, object-oriented, and lightweight interpreted (or just-in-time compiled) programming language and core technology of the web to make web pages interactive. Web browsers have a dedicated JavaScript engine that executes the client code. JavaScript is everywhere, from a small startup to a big company; most of them are working on this language to build various kinds of applications.
JavaScript is the default language of the internet. JS code can run and be tested in any web browser without creating a special development environment or any kind of setup in the text editor.
JavaScript is so beginner-friendly that anyone can learn without any previous coding experience. JS works in the web browser; there is no need to set up any kind of specific development environment.
JavaScript has a wide range of usages, including web for both frontend and backend, mobile, desktop, smartwatch, big data and cloud, game development, blockchain, automation, ML, and AI.
JavaScript is platform-independent, which means it can run on any OS, including Windows, Linux, and macOS. This makes it easy to work on different platforms and deploy on any server.
JavaScript is highly scalable and can handle large volumes of traffic without compromising performance. It is easy to add new servers to a JS application, making it simple to scale up as needed.
JavaScript frameworks are very helpful. Ex: frontend (Vue, React, and Angular.js), backend (Node, Nest, and Express.js), mobile (React Native, Flutter, Ionic, and PhoneGap), and ElectronJS for desktop.
JavaScript is a 100% free open-source programming language that is freely available for anyone to use, modify, and distribute without any cost. JavaScript can be installed quickly and at zero cost.
JavaScript is a flexible language that can be used for a wide range of web applications for both frontend and backend, mobile apps, desktop apps, games, blockchain, automation, ML, and AI.
JS is a highly secure and reliable language that has built-in security features that make it secure against common web vulnerabilities like SQL injection and cross-site scripting (XSS).
JavaScript frameworks can be integrated with a wide range of DBs and third-party applications, including PostgreSQL, MongoDB, and MySQL. This makes it easy for developers to build applications.
