js merge values of array of objects with same key in array

Question

I have an array of objects and I would like to merge all names into one array with a one liner.

[{
   id:1,
   name: 'peter'
},
{
  id:2,
  name: 'john'
}]

expected output:

['peter', 'john']

There's nothing _"merged"_ in your requirement. You only extract the value of a common property. — Andreas, Oct 24 '22 at 08:55

You can map the array to create another array with the list of names:

const people = [{
   id:1,
   name: 'peter'
},
{
  id:2,
  name: 'john'
}];

const names = people.map(({ name }) => name);
