History

JavaScript (JS) was invented in 1995 for Netscape. It is a high-level programming language that has nothing to do with Java. It was invented as a quick prototyping language rather than a fully fleshed out language. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions¹.

JS programs are run by an interpreter built into the user's web browser (not on the server). It’s typically seen as a client side language, though since the introduction of NodeJS, can now also be seen as a server side language.

Vanilla JS refers to JavaScript without frameworks or additional libraries. Scripts written in Vanilla JS are plain JS codes.
