You might just be being facetious, but in case you aren't, that's not true. The EMCAScript specification was based on JavaScript, not the other way around, and there are EMCAScript implementations that are not compatible with JavaScript (e.g. ActionScript, JScript). That is, JavaScript is one of many implementations of the EMCAScript standard, in and of itself it is not simply EMCAScript.
Nice try! ECMAScript is a standardized child of JavaScript, one with less warts and more awesome after lessons learned in javascript hell. ES6 will be nice.
I would argue the technicality you pointed out is a lot more minor than the OPs.
The OP was basically talking about the JVM as if it was a language.
*edit typo
Well, there is a Jim language, it's just not something you'd want to write by hand...
