  outer:

  while(i < 3) {

    i ++;

    let j = 0;

    while(j < 5) {

      j ++;

      if (j == 1 && i == 1) {

        continue outer

      }

      if (j == 4) break

      if (j == 3 && i == 2) {

        break outer

      }

      a.push(i * j);

    }

  }

  a.join(':')")

).unwrap();

assert_eq!(result , Value::String(String::from("2:4")));

```
