JavaScript is based on prototype programming, a multi-paradigm dynamic scripting language, and supports object-oriented, imperative, declarative, and functional programming paradigm.

The standard for JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript 5.1, and older browsers support at least the ECMAScript 3 standard.
