+  22.2.3.10 %TypedArray%.prototype.find (predicate [ , thisArg ] )
+
+  %TypedArray%.prototype.find is a distinct function that implements the same
+  algorithm as Array.prototype.find as defined in 22.1.3.8 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.
+
+  ...

+  4. If thisArg was supplied, let T be thisArg; else let T be undefined.
+  ...
+  6. Repeat, while k < len
+    ...
+    c. Let testResult be ToBoolean(? Call(predicate, T, « kValue, k, O »)).
