What is the ES of JavaScript?

The es in JavaScript stands for ECMAScript.

ECMAScript is a scripting language standardized by Ecma International (formerly the European Computer Manufacturers Association) through ECMA-262. This language is widely used on the World Wide Web and is often referred to as JavaScript or JScript, so it can be understood as a standard for JavaScript, but the latter two are actually implementations and extensions of the ECMA-262 standard.

Introduction to ECMAScript

ECMAScript is a standardized specification for a scripting language developed by Brandon Eich of Netscape; originally named Mocha, later LiveScript, and finally JavaScript. In December 1995, Sunrise and Netscape jointly published JavaScript. In November 1996, Netscape submitted JavaScript to the European Computer Manufacturers Association for standardization. The first version of ECMA-262 was adopted by Ecma in June 1997. ECMA Script is the name of the scripting language standardized by ECMA-262. Although JavaScript and JScript are compatible with ECMAScript, they contain functionality beyond ECMAScript.

ECMAScript is an object-based programming language that performs computations in a host environment and manipulates computable objects. ECMAScript was originally designed as a Web scripting language to support the dynamic rendering of Web pages and to provide server-side computing power for Web-based client-server architectures. But as a scripting language, ECMAScript has the same properties as other scripting languages, namely,"to manipulate, customize, and automate the functionality provided by an existing system."
