Question

Node.js

Hello!
There is a User model, it stores data:

{
  name: 'user',
  history: [
    { date: 01, val: 2},
    { date: 01, val: 3},
    { date: 02, val: 2}
  ]
}

Задача заключается в выдаче res.json в формате:
{
  history: [
    {
      title: 01,
      data: [
        { date: 01, val: 2},
        { date: 01, val: 3}
      ]
    },
    {
      title: 02,
      data: [
        { date: 02, val: 2},
      ]
    },
  ]
}
