What is the difference between JavaScript and ECMAScript?

Question

Is there a difference between JavaScript and ECMAScript? If there is, then what is it?

Answer 1

ECMAScript is a subset of JavaScript. JavaScript is basically ECMAScript at its core but builds upon it. Languages such as ActionScript, JavaScript, JScript all use ECMAScript as its core. As a comparison, AS/JS/JScript are 3 different cars, but they all use the same engine... each of their exteriors is different though, and there have been several modifications done to each to make it unique .
