Javascript Object Array Sorting Issue

I have a JavaScript array of objects to sort and arrange it as a new object array preserving the order.

My array of objects. I get them ordered in the way that I want. The index of the objects are 0,1 & 2 in this.

[{0: {name: 'Joel', age:25, id: 2}}, {1: {name: 'Sam', age: 23, id: 4}}, {2: {name: 'Tim', age:27, id: 3}}]

What I want is to make 'id' the index value. And I want it in ascending order of the 'name' (Preserving the above order)

[{2: {name: 'Joel', age:25, id: 2}}, {4: {name: 'Sam', age: 23, id: 4}}, {3: {name: 'Tim', age:27, id: 3}}]

I tried using this function.

for (i in members) {
    member[members[i].id] = members[i];
}

But it failed. The output was

[{}, {}, {name: "Joel", age:25, id: 2}, {name: "Tim", age:27, id: 3}, {name: "Sam", age: 23, id: 4}]

I tried using forEach and sort methods too. But all failed.

Is there any way to accomplish this in JavaScript.

You can do it with help of map and sort.

let obj = [{0: {name: 'Joel', age:25, id: 2}}, {1: {name: 'Sam', age: 23, id: 4}}, {2: {name: 'Tim', age:27, id: 3}}]


let op = obj.map((e,index)=>{
  return{
    [e[index].id] : e[index]
  }
}).sort((a,b)=> Object.keys(a) - Object.keys(b))

console.log(op)
