如何删除数组中的重复对象并保持最小值

function removeDuplicates(arr, key) {
  const hashTable = {};
  const uniqueArr = [];

  for (let i = 0; i < arr.length; i++) {
    const item = arr[i];
    const value = item[key];

    if (!hashTable[value]) {
      hashTable[value] = item;
    } else if (item < hashTable[value]) {
      hashTable[value] = item;
    }
  }

  for (const key in hashTable) {
    uniqueArr.push(hashTable[key]);
  }

  uniqueArr.sort((a, b) => a[key] - b[key]);

  return uniqueArr;
}

// 示例用法
const array = [
  { id: 1, value: 5 },
  { id: 2, value: 3 },
  { id: 3, value: 5 },
  { id: 4, value: 2 },
  { id: 5, value: 3 },
];

const uniqueArray = removeDuplicates(array, 'value');
console.log(uniqueArray);

[
  { id: 4, value: 2 },
  { id: 2, value: 3 },
  { id: 1, value: 5 },
]
