在Vue中比较两个不同的数据对象，同时减少

const obj1 = { name: 'John', age: 30 };
const obj2 = { name: 'John', age: 30 };

const isEqual = JSON.stringify(obj1) === JSON.stringify(obj2);
console.log(isEqual); // 输出true

const obj1 = { name: 'John', age: 30 };
const obj2 = { name: 'John', age: 30 };

const isEqual = Object.is(obj1, obj2);
console.log(isEqual); // 输出false

data() {
  return {
    obj1: { name: 'John', age: 30 },
    obj2: { name: 'John', age: 30 },
    isEqual: false,
  };
},
watch: {
  obj1: {
    handler() {
      this.compareObjects();
    },
    deep: true,
  },
  obj2: {
    handler() {
      this.compareObjects();
    },
    deep: true,
  },
},
methods: {
  compareObjects() {
    this.isEqual = JSON.stringify(this.obj1) === JSON.stringify(this.obj2);
  },
},

data() {
  return {
    obj1: { name: 'John', age: 30 },
    obj2: { name: 'John', age: 30 },
  };
},
computed: {
  isEqual() {
    return JSON.stringify(this.obj1) === JSON.stringify(this.obj2);
  },
},
