将数组中具有相同值的对象排序为同一数组中的一个对象

function sortObjectsWithSameValue(arr) {
  // Step 1: Create a temporary hash table
  const hashTable = {};
  for (let i = 0; i < arr.length; i++) {
    const value = arr[i].value;
    if (hashTable[value]) {
      hashTable[value].push(arr[i]);
    } else {
      hashTable[value] = [arr[i]];
    }
  }

  // Step 2: Convert hash table to result array
  const result = [];
  for (const value in hashTable) {
    if (hashTable.hasOwnProperty(value)) {
      const objects = hashTable[value];
      const mergedObject = mergeObjects(objects);
      result.push(mergedObject);
    }
  }

  // Step 3: Sort the result array
  result.sort(compareObjects);

  // Step 4: Return the sorted result array
  return result;
}

// Helper function to merge objects with the same value
function mergeObjects(objects) {
  const mergedObject = {};
  for (let i = 0; i < objects.length; i++) {
    const obj = objects[i];
    for (const key in obj) {
      if (obj.hasOwnProperty(key)) {
        mergedObject[key] = obj[key];
      }
    }
  }
  return mergedObject;
}

// Helper function to compare objects for sorting
function compareObjects(a, b) {
  // Compare based on a specific property, such as 'id'
  return a.id - b.id;
}

// Example usage
const arr = [
  { id: 1, value: 'A' },
  { id: 2, value: 'B' },
  { id: 3, value: 'A' },
  { id: 4, value: 'C' },
  { id: 5, value: 'B' },
];

const sortedArr = sortObjectsWithSameValue(arr);
console.log(sortedArr);
