How to combine relationships on normalized json with lodash?

Question

So what I have is two arrays of objects, one with people and the other with jobs like this:

[
  {
    id: 1,
    name: 'Daniel',
    job: 146
  },
  {
    id: 2,
    name: 'Jose',
    job: 163
  }
]

and:

[
  {
    id: 146,
    name: 'Developer'
  },
  {
    id: 163,
    name: 'DevOps'
  }
]

I want to obtain a single array of people where the job id is replaced with the whole job object itself, like this:

[
  {
    id: 1,
    name: 'Daniel',
    job: {
      id: 146,
      name: 'Developer'
    },
  },
  {
    id: 2,
    name: 'Jose',
    job: {
      id: 163,
      name: 'DevOps'
    }
  }
]

Maybe lodash is not the best approach, but I have no other idea. Help if you can and thank you.

Answer 1

Using Array.map and Array.find

var persons=[
  {
    id: 1,
    name: 'Daniel',
    job: 146
  },
  {
    id: 2,
    name: 'Jose',
    job: 163
  }
];

var jobs=[
  {
    id: 146,
    name: 'Developer'
  },
  {
    id: 163,
    name: 'DevOps'
  }
];

var retVal=persons.map(p=>{
return {...p,job:jobs.find(j=> j.id==p.job)};
})

console.log(retVal)
