+ 22.2.3.11 %TypedArray%.prototype.findIndex ( predicate [ , thisArg ] )
+
+ %TypedArray%.prototype.findIndex is a distinct function that implements the
+ same algorithm as Array.prototype.findIndex as defined in 22.1.3.9 except that
+ the this object's [[ArrayLength]] internal slot is accessed in place of
+ performing a [[Get]] of "length".
+
+ ...
+
+ 22.1.3.9 Array.prototype.findIndex ( predicate[ , thisArg ] )
+
+ ...
+ 3. If IsCallable(predicate) is false, throw a TypeError exception.
