How to create string array from key/value in JS?

Question

trying to create string array from key/value below code returns key/value. How do I create string array?

main.js

const array = [{
    "id": "123"
  },
  {
    "id": "124"
  }
]

console.log(Object.values(array));
const strinArray = [];

function convert() {
  for (const val of array) {
    strinArray.push(val);
  }
}

expected

["123","124"];

Your example should be a runnable snippet. And it should log the result, not the input. — Wyck

You can use map to achieve the same.

const array = [
  {"id":"123"},
  {"id":"124"}
]

console.log(array.map(item => item.id))

Took my upvote away when you mentioned IE11 and not using polyfills. Mentioning such cases is not necessary and detracts from the answer, IMO.

Well, here you go then.

You can use map() method & destructuring for this:

const array = [{ "id": "123" }, { "id": "124" } ]

console.log(array.map(({id}) => id))
