Question

for (var name in ['dog','cat','cow']) {
  alert(name);
}

The name here is returning the index of the array, but I can’t refer to it since it’s anonymous.

I know I can declare it outside the loop, but here I’m asking if is there a way for refering to the name directly that is without index.

Answer 1

If you know the keys of the array are going to be integers, there’s nothing that necessitates the use the for..in construct.

for (var arr = ['dog','cat','cow'], name = 0; name < arr.length; name++ ) {
  console.log(arr[ name ]);
}

In the above code, a simpler for loop allows for the creation of a new object and referencing by key inside the loop.
