Result can be of any type without any number conversions
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 ] )
...
7. Else initialValue is not present,
...
b. Repeat, while kPresent is false and k < len
...
iii. If kPresent is true, then
1. Let accumulator be ? Get(O, Pk).
iv. Increase k by 1.
...
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 »).
9. Return accumulator.
