基于深度嵌套数组构建对象

function buildObjectFromNestedArray(array) {
  const result = {};
  
  array.forEach((item) => {
    if (Array.isArray(item)) {
      const nestedObject = buildObjectFromNestedArray(item);
      Object.assign(result, nestedObject);
    } else {
      const [key, value] = item;
      result[key] = value;
    }
  });
  
  return result;
}

// 示例数据
const nestedArray = [
  ["name", "John"],
  ["age", 30],
  ["hobbies", ["reading", "coding"]],
  ["address", {
    "city": "New York",
    "country": "USA"
  }]
];

// 构建对象
const resultObject = buildObjectFromNestedArray(nestedArray);

console.log(resultObject);

{
  name: "John",
  age: 30,
  hobbies: ["reading", "coding"],
  address: {
    city: "New York",
    country: "USA"
  }
}
