About JavaScript

JavaScript is a programming language that allows web pages to be dynamic. It is an interpreted language, which means that it doesn’t need to be compiled: instead the interpreter (such as a web browser) will parse the code and turn it into code that their machine can run – suitable for creating dynamic websites that can run on any browser

JavaScript is not only used in the browser. JavaScript runtimes, such as Node.js and Deno allow you to write, launch and serve requests on webservers. Other frameworks, such as Electron use JavaScript to write cross-platform applications for Windows, Linux and macOS. Mobile app development is also a possibility, utilising React Native, Ionic and various others, with Expo now allowing to target Android, iOS and the web, all at once.
