+  22.2.3.12 %TypedArray%.prototype.forEach ( callbackfn [ , thisArg ] )
+
+  %TypedArray%.prototype.forEach is a distinct function that implements the same
+  algorithm as Array.prototype.forEach as defined in 22.1.3.10 except that the
+  this object's [[ArrayLength]] internal slot is accessed in place of performing
+  a [[Get]] of "length"
+
+  22.1.3.10 Array.prototype.forEach ( callbackfn [ , thisArg ] )
+
+  ...
+  6. Repeat, while k < len
+    ...
+    c. If kPresent is true, then
+      ...
+      ii. Perform ? Call(callbackfn, T, « kValue, k, O »).
