+description: Returns the same object
+info: |
+ 22.2.3.22 %TypedArray%.prototype.reverse ( )
+
+ %TypedArray%.prototype.reverse is a distinct function that implements the same
+ algorithm as Array.prototype.reverse as defined in 22.1.3.21 except that the
+ this object's [[ArrayLength]] internal slot is accessed in place of performing
+ a [[Get]] of "length".
+
+ 22.1.3.21 Array.prototype.reverse ( )
+
+ ...
+ 6. Return O.
