除了"str_repeat“之外，是否还有其他手动方法来重复该字符串？

function repeatString(string, count) {
  let repeatedString = '';
  for(let i = 0; i < count; i++) {
    repeatedString += string;
  }
  return repeatedString;
}

console.log(repeatString('abc', 3));  // 输出：abcabcabc

function repeatString(string, count) {
  if (count === 0) {
    return '';
  } else {
    return string + repeatString(string, count - 1);
  }
}

console.log(repeatString('abc', 3));  // 输出：abcabcabc
