+info: |
+  22.2.3.20 %TypedArray%.prototype.reduce ( callbackfn [ , initialValue ] )
+
+  %TypedArray%.prototype.reduce is a distinct function that implements the same
+  algorithm as Array.prototype.reduce as defined in 22.1.3.19 except that the
+  this object's [[ArrayLength]] internal slot is accessed in place of performing
+  a [[Get]] of "length".
+
+  22.1.3.19 Array.prototype.reduce ( callbackfn [ , initialValue ] )
+
+  ...
+  7. Else initialValue is not present,
+    a. Let kPresent be false.
+    b. Repeat, while kPresent is false and k < len
+      ...
+      iii. If kPresent is true, then
+        1. Let accumulator be ? Get(O, Pk).
+      ...
+  8. Repeat, while k < len
+    ...
+    c. If kPresent is true, then
+      ...
+      i. Let accumulator be ? Call(callbackfn, undefined, « accumulator, kValue,
+      k, O »).
