How to map an array of objects by a given field?

Question

I have an array of objects:

let tempArray = [
  {
    id: '1',
    name: 'Tom',
    age: 11
  },
  {
    id: '2',
    name: 'Jerry',
    age: 13
  }
  ...
]

How can I create a new array that would contain only name fields from all objects of the tempArray array?

@CodeManiac - Gah, apologies for the assumption. – T.J. Crowder Sep 03 '19 at 07:18 — T.J. Crowder, Sep 03 '19 at 07:18
Yeah, I was too quick clicking :-) @T.J.Crowder – baao Sep 03 '19 at 07:23 — baao, Sep 03 '19 at 07:23
@chrispbacon - I've **never** done that. ;-) – T.J. Crowder Sep 03 '19 at 07:23 — T.J. Crowder, Sep 03 '19 at 07:23

Trying using map()

let tempArray = [
    {
        id: '1',
        name: 'Tom',
        age: 11
    },
    {
        id: '2',
        name: 'Jerry',
        age: 13
    }
]

const res = tempArray.map(i => i.name)
console.log(res)
