You can check which version of ECMAScript a browser is using by opening the browser's Developer Tools and looking at the JavaScript Console. The console will usually list the version of ECMAScript that the browser is using.About ECMAScript
ECMAScript (or ES) is a general-purpose programming language, standardized by ECMA International according to the document ECMA-262.First, it is important to mention that ECMA is an organization that makes and publishes standards in programming. The standard ECMA-262 was published with the intention to define and establish general features that programming languages should have. It can be confusing thinking of ECMA Script as a language when we already know that ECMA itself regulates programming languages in general.
