+  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".

+  ...
+  4. If argument fromIndex was passed, let n be ? ToInteger(fromIndex); else let
+  n be len-1.
