如何检测javascript中JSON的差异？

function compareJSON(obj1, obj2) {
  // 检查类型
  if (typeof obj1 !== typeof obj2) {
    return "类型不同";
  }

  // 检查基本类型
  if (typeof obj1 !== "object" || obj1 === null || obj2 === null) {
    if (obj1 !== obj2) {
      return "值不同";
    }
    return "相同";
  }

  // 检查数组
  if (Array.isArray(obj1)) {
    if (obj1.length !== obj2.length) {
      return "数组长度不同";
    }
    for (let i = 0; i < obj1.length; i++) {
      const result = compareJSON(obj1[i], obj2[i]);
      if (result !== "相同") {
        return `数组元素 ${i} 不同: ${result}`;
      }
    }
    return "相同";
  }

  // 检查对象
  const keys1 = Object.keys(obj1);
  const keys2 = Object.keys(obj2);
  if (keys1.length !== keys2.length) {
    return "对象属性数量不同";
  }
  for (let key of keys1) {
    const result = compareJSON(obj1[key], obj2[key]);
    if (result !== "相同") {
      return `属性 ${key} 不同: ${result}`;
    }
  }
  return "相同";
}

// 示例用法
const json1 = { name: "John", age: 30, hobbies: ["reading", "coding"] };
const json2 = { name: "John", age: 25, hobbies: ["reading", "gaming"] };

const result = compareJSON(json1, json2);
console.log(result);
