+description: search element is compared using strict comparing (===)
+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 ] )
+
+ ...
+ 7. Repeat, while k ≥ 0
+ ...
+ b. If kPresent is true, then
+ i. Let elementK be ? Get(O, ! ToString(k)).
+ ii. Let same be the result of performing Strict Equality Comparison
+ searchElement === elementK.
+ iii. If same is true, return k.
