Is it possible to access to an object based on a parameter on this function?

function fnc (num) {
  const obj1 = { whatever : "foo1"}
  const obj2 = { whatever : "foo2"}
  return console.log([`obj${num}`].whatever)
}

fnc(1) // Expected Result foo1 but got undefined

Also tried with same result

`obj${num}`.whatever

Any idea? Thank you!!

This looks like a job for an *array* rather than numbered variables, no? – David Jan 24 '23 at 17:29
Some languages allow that sort of thing. JavaScript isn't one of them. Use an array. – Pointy Jan 24 '23 at 17:30
Trying to acces to const idRef = useRef(null); but I have multiple of them (const addressRef = useRef(null); ...) and I need to somehow have a parameter in the function and add to it the "Ref" in order to be able to access – Ewejnog Jan 24 '23 at 17:33
not going to happen. Use an object/set with keys or an array. – epascarello Jan 24 '23 at 17:36
`const myRefs = useRef({});` – Quentin Jan 24 '23 at 17:37
