description: handle Infinity values for 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.
6. Else n < 0,
a. Let k be len + n.
b. If k < 0, let k be 0.
7. Repeat, while k < len
...
8. Return false.
