What is ecmascript?

ECMAScript is a scripting language specification defined by Ecma International (formerly the European Computer Manufacturers Association) in standard ECMA-262. This language is widely used on the World Wide Web. It is often called JavaScript or JScript, but in fact the latter two are implementations and extensions of the ECMA-262 standard.

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.

History:
ECMAScript is a standardized specification for a scripting language developed by Brandon Ek of Netscape; originally named Mocha, later renamed LiveScript, and finally renamed JavaScript. In December 1995, Sun and Netscape jointly released JavaScript[2]. 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. ECMAScript is the name of the scripting language standardized by ECMA-262.
Although JavaScript and JScript are compatible with ECMAScript, they contain functionality beyond ECMAScript.
