specific array values into another array typescript?

Question

 "info": [
    {
        "Name": "sda",
        "Icon": null,
        "id": 45
    },
    {
        "Name": "srda",
        "Icon": null,
        "id": 47 
    }]

i have an array of this json body / model class . I need to put only ids into another array in typescript.

I'm guessing it's a duplicate, anyway just use map funciton of array: https://developer.mozilla.org/tr/docs/Web/JavaScript/Reference/Global_Objects/Array/map — halilcakar, Jun 27 '20 at 22:09
@Esdras - please specify the expected output format and an example values. — Rahul Bhobe, Jun 27 '20 at 22:26
yes - but OP does not specify what format. `[45, 47]` or `[{id: 45}, {id: 47}]`. — Rahul Bhobe, Jun 28 '20 at 00:39

You can use map operator for this

var el={
"info": [
    {
        "Name": "sda",
        "Icon": null,
        "id": 45
    },
    {
        "Name": "srda",
        "Icon": null,
        "id": 47 
    }]
}
var result=el.info.map(x=>x.id);
console.log(result);
