May be I should have been a bit more precise: implement (essential part of) array protocol, because the following works:
```
>var arr = new Array(70, 82, 65, 77, 64, 53, 49, 50);
=[ 70, 82, 65, 77, 64, 53, 49, 50 ]
="FRAM@512"
> 
```
and so does
```
>String.fromCharCode.apply(null,[70, 82, 65, 77, 64, 53, 49, 50]);
="FRAM@512"
> 
```
All browser's w/ name do too, because of MDN's String and Function definition (fromCharCode() and call()).
The the statement is a valid statement -

Regarding your suggestion: I tried to avoid in a loop the in and out of the JS engine AND the String concatenation.

What about overall performance - Is string concatenation not the recipe for increased garbage collection activities? ...of course, 'it all depends', since many things in a system contribute combined to results for better or worse.

Why I was looking for this is for my FRAMS module, where this construct comes in very handy for reading back as a String (see http://forum.espruino.com/conversations/257994).
