如何:检索和检查数组中的嵌套对象

const data = [
  { id: 1, name: 'Alice', details: { age: 25, city: 'New York' } },
  { id: 2, name: 'Bob', details: { age: 30, city: 'Los Angeles' } },
  { id: 3, name: 'Charlie', details: { age: 35, city: 'Chicago' } }
];

const result = data.find(item => item.name === 'Alice');
console.log(result); // { id: 1, name: 'Alice', details: { age: 25, city: 'New York' } }

const hasCity = data.some(item => item.details.city === 'Chicago');
console.log(hasCity); // true

function traverseArray(arr) {
  arr.forEach(item => {
    if (Array.isArray(item)) {
      traverseArray(item);
    } else {
      console.log(item);
    }
  });
}

const multiDimensionalArray = [1, [2, [3, 4], 5], 6];
traverseArray(multiDimensionalArray);
// 输出: 1, 2, 3, 4, 5, 6

function getNestedProperty(obj, path) {
  return path.split('.').reduce((acc, part) => acc && acc[part], obj);
}

const obj = { user: { profile: { name: 'John' } } };
console.log(getNestedProperty(obj, 'user.profile.name')); // John
console.log(getNestedProperty(obj, 'user.profile.age')); // undefined
