在二维中打印嵌套对象

function printNestedObject(obj, indent = 0) {
  for (let key in obj) {
    if (typeof obj[key] === 'object') {
      console.log(`${' '.repeat(indent)}${key}:`);
      printNestedObject(obj[key], indent + 2);
    } else {
      console.log(`${' '.repeat(indent)}${key}: ${obj[key]}`);
    }
  }
}

const nestedObject = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  },
  hobbies: ['reading', 'coding', 'gaming']
};

printNestedObject(nestedObject);
