Would that exercise be the following? I'm not sure I understand what's being tested.

  const f = (k) => {
    const funcs = [];
    for(let i = 0; i < k; i++) {
      funcs.push(() => i);
    }
    return funcs;
  }

  const test = f(4);
  console.log(test[0]()); // 0
  console.log(test[1]()); // 1
  console.log(test[2]()); // 2
  console.log(test[3]()); // 3
