description: >
Integer indexed values are not cached before iteration
info: |
22.2.3.21 %TypedArray%.prototype.reduceRight ( callbackfn [ , initialValue ] )
%TypedArray%.prototype.reduceRight is a distinct function that implements the
same algorithm as Array.prototype.reduceRight as defined in 22.1.3.20 except
that the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length".
22.1.3.20 Array.prototype.reduceRight ( callbackfn [ , initialValue ] )
...
8. Repeat, while k ≥ 0
...
c. If kPresent is true, then
i. Let kValue be ? Get(O, Pk).
ii. Let accumulator be ? Call(callbackfn, undefined, « accumulator,
kValue, k, O »).
d. Decrease k by 1.
