1071668 - Implement array methods on %TypedArray%

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Florian Scholz (Open Web Docs)]

In the current ES6 spec, Array.prototype methods are present on %TypedArray%.prototype as well:

%TypedArray%.prototype.copyWithin - implemented in bug 1021379
%TypedArray%.prototype.entries
%TypedArray%.prototype.every
%TypedArray%.prototype.fill
%TypedArray%.prototype.filter
%TypedArray%.prototype.find
%TypedArray%.prototype.findIndex
%TypedArray%.prototype.forEach
%TypedArray%.prototype.indexOf
%TypedArray%.prototype.join
%TypedArray%.prototype.key
%TypedArray%.prototype.lastIndexOf
%TypedArray%.prototype.map
%TypedArray%.prototype.reduce
%TypedArray%.prototype.reduceRight
%TypedArray%.prototype.reverse
%TypedArray%.prototype.slice
%TypedArray%.prototype.some
%TypedArray%.prototype.sort
%TypedArray%.prototype.values - also not on Array yet, see bug 875433.

%TypedArray%.{of, from} is bug 896608

Definitions start here:

See also this v8 issue: https://code.google.com/p/v8/issues/detail?id=3578

We might want separate bugs for these methods, in that case this bug could act as a tracking bug.

In case anyone's thinking of working on these: *please* *please* do them self-hosted.  (This will be far easier after bug 896116 lands, soon.  We'll need to add an intrinsic or two to help out, but it should be easy enough.)  C++ implementations for this are more fragile than I care to accept, and indeed I plan to self-host the current C++ functions Real Soon Now after that bug lands.

Nice progress so far! :)

fwiw, it seems like I forgot 

%TypedArray%.prototype.toString
%TypedArray%.prototype.toLocaleString

in the list above.
