合并具有相同属性值的数组内的对象

function mergeObjectsByProperty(arr) {
  return arr.reduce((result, obj) => {
    const existingObj = result.find(item => item.property === obj.property);
    if (existingObj) {
      Object.assign(existingObj, obj);
    } else {
      result.push(obj);
    }
    return result;
  }, []);
}

// 示例用法
const arr1 = [{ property: 'A', value: 1 }, { property: 'B', value: 2 }];
const arr2 = [{ property: 'A', name: 'John' }, { property: 'C', name: 'Jane' }];
const mergedArray = mergeObjectsByProperty([...arr1, ...arr2]);
console.log(mergedArray);
