How to take id and make array from array of object

Question

var arrayOfObj = [{id: 41, uid: "62d0e9d5-25d4"},
        {id: 42, uid: "62d0e9d5-25d4},
        {id: 43, uid: "62d0e9d5-25d4},
        {id: 44, uid: "62d0e9d5-25d4}];

expected result: a= [41,42,43];

Try this `const result = arrayOfObj.map(item => item.id);` – Venkat.R Mar 11 '19 at 17:13 — Venkat.R, Mar 11 '19 at 17:13
Why `44` is not in expected result? – brk Mar 11 '19 at 17:14 — brk, Mar 11 '19 at 17:14

You can do it with javascript map function. Read the docs here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
