如何在JavaScript中获取关联数组中最深的对象？

function getDeepestObject(obj) {
  let deepest = null;
  let maxDepth = 0;

  function traverse(obj, depth) {
    if (typeof obj !== 'object' || obj === null) {
      return;
    }

    if (depth > maxDepth) {
      deepest = obj;
      maxDepth = depth;
    }

    for (let key in obj) {
      traverse(obj[key], depth + 1);
    }
  }

  traverse(obj, 1);

  return deepest;
}

const data = {
  a: {
    b: {
      c: {
        d: 'deepest'
      }
    }
  },
  e: {
    f: 'not deepest'
  }
};

const deepestObject = getDeepestObject(data);
console.log(deepestObject); // 输出: { d: 'deepest' }
