22.2.3.12 %TypedArray%.prototype.forEach ( callbackfn [ , thisArg ] )
%TypedArray%.prototype.forEach is a distinct function that implements the same
algorithm as Array.prototype.forEach as defined in 22.1.3.10 except that the
this object's [[ArrayLength]] internal slot is accessed in place of performing
a [[Get]] of "length"
22.1.3.10 Array.prototype.forEach ( callbackfn [ , thisArg ] )
...
4. If thisArg was supplied, let T be thisArg; else let T be undefined.
...
6. Repeat, while k < len
...
c. If kPresent is true, then
...
ii. Perform ? Call(callbackfn, T, « kValue, k, O »).
