+ 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.
+
+ ...
+
+ 22.1.3.8 Array.prototype.find ( predicate[ , thisArg ] )
+
+ ...
+ 6. Repeat, while k < len
+ ...
+ c. Let testResult be ToBoolean(? Call(predicate, T, « kValue, k, O »)).
+ d. If testResult is true, return kValue.
