What is es of javascript?

javascript's es refers to ECMAScript.

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

Introduction to ECMAScript

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

ECMAScript is an object-based programming language that can perform calculations in a host environment and manipulate computable objects. ECMAScript was first designed as a Web scripting language to support the dynamic presentation of Web pages and provide server-side computing capabilities for Web-based client-server architectures. But as a scripting language, ECMAScript has the same nature as other scripting languages, that is, "used to manipulate, customize, and automate the functions provided by an existing system."
