One would be wrong, then.  ECMAScript is a standard for object-oriented 
programming languages, precisely scripting languages ("programming 
language[s] that [are] used to manipulate, customise, and automate the 
facilities of an existing system") [1].  JavaScript, JScript, and 
ActionScript are some of the different implementations of that standard that 
(sometimes conformingly) differ from the standard and from each another; 
they are ECMAScript implementations.

It is important to make that distinction, not least because it matters which 
implementation is being talked about, as it is the host environment that 
defines the implementation that is used.  In this case, the ECMAScript 
implementation that was being referred to with "javascript" was probably, 
but not necessarily, Google V8 3.7.12.12 or later in Google Chrome 
17.0.963.78 or later [2].

include the results of my current work is coming in a few months from now).
