For

Wing supports looping over collections with for..in statements.

for..in is used to iterate over an array, a set or a range.

main.w

// a standard for loop
for item in 1..3 {
  log(item);
}

// for-in with arrays
let arr = [1, 2, 3];
for item in arr {
  log(item);
}

// break a loop
let items = Set<num>[1, 2, 3];
for item in items {
  if item == 1 {
    break;
  }
  log(item);
}

// continue the next iteration of the loop
for item in 1..10 {
  if item % 2 == 0 {
    continue;
  }
  log(item);
}
