const promise1 = new Promise((resolve, reject) => {
       resolve({"id" : "123456789"});
    });

function x (i){
    let id;
    let amt=i;
    promise1.then((value) => {
      id = value.id;
    });
    
    return {
        "id": id,
        "amount": amt
    }
}
let arr=[];
for(let b = 0; b < 3; b++){
    arr[b]=x(b)
}

console.log(arr)

Output:

    [ { id: undefined, amount: 0 },
  { id: undefined, amount: 1 },
  { id: undefined, amount: 2 } ]

I am having logical problem in this code Why is unidentified being shown in the output? please help!!!
