ECMAScript _implementation*s*_.  (I know that you probably know this: )

It is vital to understand (which is why I do not tire to point it out) that 
there is not only one such scripting language as ECMAScript implementations 
differ from one another.  For example, you will already find some features 
of ECMAScript Ed. 6/2015 in Mozilla JavaScript, but not yet in Google V8 
JavaScript (the more Canary, the more likely that you find them there, too).

If you write your code only based on superficial reading of MDN (neglecting 
the top or bottom section of articles), and test it only in Firefox or 
Seamonkey because you are thinking “JavaScript”, it can *break* in 
Chromium/Chrome even if it is syntactically correct (or *considered* 
syntactically correct by Firefox’s script engine; there are also syntax 
extensions in implementations, in *full compliance* with the Specification 
text).  And those are only two implementations and two runtime environments 
of much more.

Which is referred to in the “FAQ for comp.lang.javascript” (see below), 
thanks to you :)
