How to sort nested obj javascript

Question

I tried to sort object by date. I must use es5 because it's in angularjs This is what I tried but no luck.

let objtemp = {
  1: {
    first: 0,
    created: "2020-11-03T14:16:51.319Z"
  },
  2: {
    first: 2,
    created: "2020-11-03T14:01:32.084Z"
  },
  3: {
    first: 2,
    created: "2020-11-03T14:00:47.000Z"
  }
};
let temp = Object.entries(objtemp);
temp.sort(function([a, aval], [b, bval]) {
  return new Date(bval.created).getTime() - new Date(aval.created).getTime();
});
console.log(temp);

The result I get :

{1:{first:0, created: "2020-11-03T14:16:51.319Z"}, 2:{first:2, created: "2020-11-03T14:01:32.084Z"}, 3:{first:2, created:"2020-11-03T14:00:47.000Z"}}

Expected result is

{3:{first:2, created:"2020-11-03T14:00:47.000Z"},2:{first:2, created: "2020-11-03T14:01:32.084Z"},1:{first:0, created: "2020-11-03T14:16:51.319Z"}}

"The result I get" That definitely isn't the result you get, because you've logged temp, which is an array, but you've shown a non-array object. — T.J. Crowder

Why is the input an object with "numeric" keys and not an actual array? — Andreas

Your sort check is opposite of what you need.... return new Date(aval.created).getTime() - new Date(bval.created).getTime(); — epascarello

Side note: A more concise way to write new Date(x).getTime() (where x is a string) is Date.parse(x). They do the same thing, the latter is just less work. — T.J. Crowder

temp.sort(function([a, aval], [b, bval]) {
  return new Date(aval.created).getTime() - new Date(bval.created).getTime();
});

Problem was the sort check was opposite to what I needed. Thanks to @epascarello
