esid: sec-%typedarray%.prototype.reduceright
description: >
Returns [0] without calling callbackfn if length is 1 and initialValue is not
present.
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 ] )
...
7. Else initialValue is not present,
...
b. Repeat, while kPresent is false and k ≥ 0
...
ii. Let kPresent be ? HasProperty(O, Pk).
iii. If kPresent is true, then
1. Let accumulator be ? Get(O, Pk).
iv. Decrease k by 1.
...
8. Repeat, while k ≥ 0
...
9. Return accumulator.
