javascript - 将对象数组中两个属性的唯一值存储到单个数组中

如何获取requesterPractitionerId和performerOrganizationId的唯一值。我需要在单个数组中探索requesterPractitionerId和performerOrganizationId的唯一值。

[
    {
        id: '1043120',
        requesterPractitionerId: '1043119',
    },
    {
        id: '1043081',
        requesterPractitionerId: '1043080'
    },
    {
        id: 'e1dceebe-c5ba-46a5-a63a-bff709896af4',
        requesterPractitionerId: 'e0a844e4-6c8a-489a-8bd6-1d62267d311e',
        performerOrganizationId: '05D0889009',
    },
    {
        id: '2709842f-41e3-4193-8607-fc34d3d24ec1',
        requesterPractitionerId: 'e0a844e4-6c8a-489a-8bd6-1d62267d311e',
        performerOrganizationId: '05D0889009'
    }
]

预期产量：

1043119
1043080
e0a844e4-6c8a-489a-8bd6-1d62267d311e
05D0889009

我是Java语言的新手，并为此奋斗了两个小时。任何帮助将不胜感激。

最佳答案

使用Set，Array.reduce和Array.from


使用reduce创建具有所述字段的唯一值的集合
然后使用Array.from将集合转换为数组

let arr = [{id:'1043120',requesterPractitionerId:'1043119'},{id:'1043081',requesterPractitionerId:'1043080'},{id:'e1dceebe-c5ba-46a5-a63a-bff709896af4',requesterPractitionerId:'e0a844e4-6c8a-489a-8bd6-1d62267d311e',performerOrganizationId:'05D0889009'},{id:'2709842f-41e3-4193-8607-fc34d3d24ec1',requesterPractitionerId:'e0a844e4-6c8a-489a-8bd6-1d62267d311e',performerOrganizationId:'05D0889009'}];

let result = Array.from(arr.reduce((a,c) => {
  if(c.requesterPractitionerId) a.add(c.requesterPractitionerId);
  if(c.performerOrganizationId) a.add(c.performerOrganizationId);
  return a;
}, new Set()));

console.log(result);
