I'm missing something or I may need a work around

I am trying to build an array of objects. I want the key to be a value of a variable but my code is inserting a literal. Thank you for any assistance.

I want to generate
resArr [ { 0: { ‘0’: 3, ‘1’: 2, ‘2’: 8 } },
{ 1: { ‘0’: 4, ‘1’: 4, ‘2’: 5 } },
{ 2: { ‘0’: 3, ‘1’: 7, ‘2’: 2 } } ]

but I get
resArr [ { pos: { ‘0’: 3, ‘1’: 2, ‘2’: 8 } },
{ pos: { ‘0’: 4, ‘1’: 4, ‘2’: 5 } },
{ pos: { ‘0’: 3, ‘1’: 7, ‘2’: 2 } } ]

code:

let x = [ {0:3, 1:2, 2:8}, {0:4, 1:4, 2:5}, {0:3, 1:7, 2:2} ];
let resArr = [];
let pos = 0;
let oby;

x.forEach(function(ele) {
	oby = {pos : ele};
	console.log(ele);
	resArr.push(oby);
    pos++;	
});
console.log("resArr", resArr);

fantastic, thank you.
