For Loop

Two types of for loops are allowed:

for (int month = 1; month <= 12; month++) {
  print(month);
}

and:

for (var object in flybyObjects) {
  print(object);
}

The for-in loop is convenient when simply iterating over an Iterable collection. There is also a forEach method that you can call on Iterable objects that behaves like for-in:

flybyObjects.forEach((object) => print(object));

or, more concisely:

flybyObjects.forEach(print);
