+  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 ( )
