如何为某些复制重复一个带数字的字符串

function duplicateString(originalString, n) {
  let duplicatedString = '';
  for (let i = 1; i <= n; i++) {
    duplicatedString += originalString + i;
  }
  return duplicatedString;
}

const originalString = 'abc';
const n = 3;
const result = duplicateString(originalString, n);
console.log(result); // 输出：abc1abc2abc3
