按公共属性对对象进行分组，将其余属性合并为数组中的单独对象

function groupObjectsByCommonProperty(objects) {
  const hashTable = {};
  
  // 遍历所有对象，按公共属性进行分组
  for (const obj of objects) {
    const commonProperty = obj.commonProperty;
    
    if (commonProperty in hashTable) {
      hashTable[commonProperty].push(obj);
    } else {
      hashTable[commonProperty] = [obj];
    }
  }
  
  const result = [];
  
  // 遍历哈希表，将值合并为单独对象
  for (const commonProperty in hashTable) {
    const mergedObject = {
      commonProperty: commonProperty,
      values: hashTable[commonProperty]
    };
    
    result.push(mergedObject);
  }
  
  return result;
}

// 示例对象数组
const objects = [
  { commonProperty: 'A', otherProperty: 'A1' },
  { commonProperty: 'B', otherProperty: 'B1' },
  { commonProperty: 'A', otherProperty: 'A2' },
  { commonProperty: 'C', otherProperty: 'C1' },
  { commonProperty: 'B', otherProperty: 'B2' },
];

// 调用函数进行分组和合并
const groupedObjects = groupObjectsByCommonProperty(objects);

console.log(groupedObjects);

[
  {
    commonProperty: 'A',
    values: [
      { commonProperty: 'A', otherProperty: 'A1' },
      { commonProperty: 'A', otherProperty: 'A2' }
    ]
  },
  {
    commonProperty: 'B',
    values: [
      { commonProperty: 'B', otherProperty: 'B1' },

    ]
