esid: sec-%typedarray%.prototype.reduce
description: >
Integer indexed values are not cached before iteration
info: |
22.2.3.20 %TypedArray%.prototype.reduce ( callbackfn [ , initialValue ] )
%TypedArray%.prototype.reduce is a distinct function that implements the same
algorithm as Array.prototype.reduce as defined in 22.1.3.19 except that the
this object's [[ArrayLength]] internal slot is accessed in place of performing
a [[Get]] of "length".
22.1.3.19 Array.prototype.reduce ( callbackfn [ , initialValue ] )
...
8. Repeat, while k < len
...
c. If kPresent is true, then
i. Let kValue be ? Get(O, Pk).
ii. Let accumulator be ? Call(callbackfn, undefined, « accumulator, kValue,
k, O »).
