description: get the integer value from fromIndex
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 ] )
...
4. Let n be ? ToInteger(fromIndex). (If fromIndex is undefined, this step
produces the value 0.)
5. If n ≥ 0, then
a. Let k be n.
...
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.
8. Return false.
