esid: sec-%typedarray%.prototype.includes
description: search element is compared using SameValueZero
info: |
22.2.3.13 %TypedArray%.prototype.includes ( searchElement [ , fromIndex ] )
%TypedArray%.prototype.includes is a distinct function that implements the
same algorithm as Array.prototype.includes as defined in 22.1.3.11 except that
the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length".
22.1.3.11 Array.prototype.includes ( searchElement [ , fromIndex ] )
...
7. Repeat, while k < len
a. Let elementK be the result of ? Get(O, ! ToString(k)).
b. If SameValueZero(searchElement, elementK) is true, return true.
c. Increase k by 1.
