for循环中的setTimeout不会打印连续值

function printValues(i, n) {
  if (i > n) {
    return;
  }
  setTimeout(function() {
    console.log(i);
    printValues(i + 1, n);
  }, 1000);
}
printValues(1, 5);

function delay(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

async function printValues(n) {
  for (let i = 1; i <= n; i++) {
    await delay(1000);
    console.log(i);
  }
}
printValues(5);
