如何将数组中对象的每个值都转换为字符串

function convertArrayValuesToStrings(arr) {
  for (let i = 0; i < arr.length; i++) {
    const obj = arr[i];
    for (let key in obj) {
      if (typeof obj[key] !== 'string') {
        obj[key] = obj[key].toString();
      }
    }
  }
  return arr;
}

// 示例用法
const arr = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Bob', age: 35 }
];

const convertedArr = convertArrayValuesToStrings(arr);
console.log(convertedArr);
