Javascript Scripting Language
JavaScript, often abbreviated as JS, is a both (client-side but also server-side) scripting language that conforms to the ECMAScript specification.
Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web.
JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions.
