Iterator in haXe

Iterator, as the name suggests, is an object that iterates all the elements of a collection. In haXe, iterator follows iterator typedef:
typedef Iterator = {
function hasNext() : Bool;
function next() : T;
}
The type T denotes the iterator type.
The simplest iterator is the IntIter iterator. We can easily built it with ...(three dots). The syntax is:
for( i in 0...100 ) {
// ...
}
We don’t need to declare the type of variable i, since it is automatically declared.
