info: |
22.2.3.17 %TypedArray%.prototype.lastIndexOf ( searchElement [ , fromIndex ] )
%TypedArray%.prototype.lastIndexOf is a distinct function that implements the
same algorithm as Array.prototype.lastIndexOf as defined in 22.1.3.15 except
that the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length".
22.1.3.15 Array.prototype.lastIndexOf ( searchElement [ , fromIndex ] )

5. If n ≥ 0, then
a. If n is -0, let k be +0; else let k be min(n, len - 1).
