javascript - 如何合并嵌套对象数组的内容？

Question

我有一个名为 allLeads 的对象数组，它存储数组中每个项目的 leadName 和 leadId 以及一个名为 Leads 的项目这是另一个对象数组。

但目前我从后端接收数据的方式是，leads 数组一次仅存储一个对象。我想为每个 leadId 和 leadName 合并此潜在客户数组。

目前情况如何

const allLeads = [
  {
    leadName: "software development",
    leadId: 123,
    leads: [{ profile: "hello", url: "bye" }]
  },
  {
    leadName: "software development",
    leadId: 123,
    leads: [{ profile: "lets", url: "go" }]
  },
  {
    leadName: "business development",
    leadId: 234,
    leads: [{ profile: "dont", url: "try" }]
  },
  {
    leadName: "business development",
    leadId: 234,
    leads: [{ profile: "other", url: "side" }]
  }
];

我想要怎样

const allLeads = [
  {
    leadName: "software development",
    leadId: 123,
    leads: [{ profile: "hello", url: "bye" }, { profile: "lets", url: "go" }]
  },
  {
    leadName: "business development",
    leadId: 234,
    leads: [{ profile: "dont", url: "try" }, { profile: "other", url: "side" }]
  }
];

const allLeads = [
  {
    leadName: "software development",
    leadId: 123,
    leads: [{ profile: "hello", url: "bye" }]
  },
  {
    leadName: "software development",
    leadId: 123,
    leads: [{ profile: "lets", url: "go" }]
  },
  {
    leadName: "business development",
    leadId: 234,
    leads: [{ profile: "dont", url: "try" }]
  },
  {
    leadName: "business development",
    leadId: 234,
    leads: [{ profile: "other", url: "side" }]
  }
];
function handle(array) {
  let obj = array.reduce((acc, cur) => {
    acc[cur.leadId] = acc[cur.leadId] || {};
    acc[cur.leadId].leads = acc[cur.leadId].leads || [];
    acc[cur.leadId].leadName = cur.leadName;
    acc[cur.leadId].leadId = cur.leadId;
    acc[cur.leadId].leads.push(...cur.leads);
    return acc;
  }, {});
  return Object.values(obj);
}
  console.log(handle(allLeads))
