如何首先组合对象的属性，然后使用Javascript删除对象数组中的重复项

const obj1 = { name: 'John', age: 25 };
const obj2 = { gender: 'Male', occupation: 'Engineer' };

const combinedObj = Object.assign({}, obj1, obj2);
console.log(combinedObj);
// 输出: { name: 'John', age: 25, gender: 'Male', occupation: 'Engineer' }

function removeDuplicates(arr) {
  const uniqueObjects = {};
  const uniqueArray = [];

  for (let obj of arr) {
    const objString = JSON.stringify(obj);

    if (!uniqueObjects[objString]) {
      uniqueObjects[objString] = true;
      uniqueArray.push(obj);
    }
  }

  return uniqueArray;
}

const objectsArray = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 1, name: 'John' },
  { id: 3, name: 'Mike' }
];

const uniqueArray = removeDuplicates(objectsArray);
console.log(uniqueArray);
// 输出: [ { id: 1, name: 'John' }, { id: 2, name: 'Jane' }, { id: 3, name: 'Mike' } ]
