For

Wing supports for..in statements.

for..in is used to iterate over an array, a set or a range. The loop invariant in for loops is implicitly re-assignable (var).

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);
}
