Q57

Which exception does the Iterators throw from their next() method when there are no more values to iterate, that work on finite collections ?

A.
ExitIteration
B.
AbortIteration
C.
Abort
D.
StopIteration
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
Iterators that work on finite collections throw StopIteration from their next() method when there are no more values to iterate. StopIteration is a property of the global object in JavaScript 1.7. Its value is an ordinary object (with no properties of its own) that is reserved for this special purpose of terminating iterations. Note, in particular,that StopIteration is not a constructor function like TypeError() or RangeError().
