+  22.2.3.8 %TypedArray%.prototype.fill (value [ , start [ , end ] ] )
+
+  %TypedArray%.prototype.fill is a distinct function that implements the same
+  algorithm as Array.prototype.fill as defined in 22.1.3.6 except that the this
+  object's [[ArrayLength]] internal slot is accessed in place of performing a
+  [[Get]] of "length". The implementation of the algorithm may be optimized with
+  the knowledge that the this value is an object that has a fixed length and
+  whose integer indexed properties are not sparse. However, such optimization
+  must not introduce any observable changes in the specified behaviour of the
+  algorithm.

+    b. Perform ? Set(O, Pk, value, true).
