将嵌套数组的第一个元素指定为父对象的属性

function assignNestedArray(nestedArray) {
  const parentObject = {};

  nestedArray.forEach(subArray => {
    const propertyName = subArray[0];
    const propertyValue = subArray.slice(1);

    parentObject[propertyName] = propertyValue;
  });

  return parentObject;
}

// 示例嵌套数组
const nestedArray = [
  ['name', 'John'],
  ['age', 25],
  ['hobbies', ['reading', 'painting']],
  ['address', { street: '123 Main St', city: 'New York' }]
];

// 调用函数将嵌套数组的第一个元素指定为父对象的属性
const result = assignNestedArray(nestedArray);

console.log(result);

{
  name: ['John'],
  age: [25],
  hobbies: ['reading', 'painting'],
  address: { street: '123 Main St', city: 'New York' }
}
