我有一个对象数组。
我需要将它们转换为。

我已经通过部分使用lodash和vanilla js来实现,它完全正常工作。但从可读性的角度来看,它完全不好。我想只使用lodash来完成这个任务。有什么帮助吗?
let ids: any = groupBy(this.project.work, function (res) {
return res.employee._id;
});
for (let id in ids) {
let tmp = [];
let employee_added = false;
ids[id].map((work) => {
if (!employee_added) {
tmp = work.employee;
tmp['work'] = [];
employee_added = true;
}
delete work.employee;
tmp['work'].push(work);
})
this.employees.push(tmp);
}
console.log(this.employees);
omit
,而是将其余属性作为{employee, ...rest}
并使用rest
