ECMAScript

ECMAScript (/ˈɛkməskrɪpt/) (or ES)[1] is a general-purpose programming language, standardised by Ecma International according to the document ECMA-262. It is a JavaScript standard meant to ensure the interoperability of web pages across different web browsers.[2] ECMAScript is commonly used for client-side scripting on the World Wide Web, and it is increasingly being used for writing server applications and services using Node.js. https://en.wikipedia.org/wiki/ECMAScript
