选择嵌套数组对象并替换它

function replaceNestedArrayObject(arr, target, replacement) {
  for (let i = 0; i < arr.length; i++) {
    if (Array.isArray(arr[i])) {
      replaceNestedArrayObject(arr[i], target, replacement); // 递归调用
    } else if (typeof arr[i] === 'object') {
      for (let key in arr[i]) {
        if (arr[i][key] === target) {
          arr[i][key] = replacement;
        }
      }
    }
  }
}

// 示例用法
const nestedArray = [
  { id: 1, name: 'John', children: [{ id: 2, name: 'Alice' }] },
  { id: 3, name: 'Bob', children: [{ id: 4, name: 'Eve' }] }
];

const target = 'Alice';
const replacement = 'Mia';

replaceNestedArrayObject(nestedArray, target, replacement);

console.log(nestedArray);
