JavaScript

JavaScript is a high-level, interpreted programming language that conforms to the ECMAScript specification. It is a multi-paradigm language that supports object-oriented, imperative, and functional programming styles.

Hello, World!

console.log("Hello, World!");

Being more advanced…

JavaScript can be used in two ways: for client-side (frontend) development and for server-side (backend) development. More advanced topics therefore mainly include server-side I/O, performance optimization, and very advanced language features such as WeakMap, Proxy, asynchronous iteration, generators, and more.
