I have an Object like this:

let arr ={
1.2 : 44,
55: 41,
13: 59,
2.3 : 77
}

console.log(Object.fromEntries(Object.entries(arr).sort()))

//   Result: 
//  {
//    "13": 59,
//    "55": 41,
//    "1.2": 44,
//    "2.3": 77
//  }

//   Expected Result: 
//  {
//    "1.2": 44,
//    "2.3": 77,
//    "13": 59,
//    "55": 41
//  }

The sort function treats keys as string and not floating point numbers.

I've tried Lodash Sort too, but no luck.

Any help would be appreciated.

    13 and 55 will always be on top because integer keys are enumerated in ascending order before other keys. – adiga Apr 26 '21 at 09:12

    @adiga you're too fast - went to edit in the ES6 ordering dupes and they were already there :D – VLAZ Apr 26 '21 at 09:13

    At any rate, that's correct - keys that contain non-negative integers will always be 1. sorted first 2. sorted in order. If order is important *do not rely on object keys*. Use a different structure that defines the order via an array - using objects: `[{id: 1.2, value: 44}, { id: 2.3, value: 77}]` or using an array of pairs `[[1.2, 44], [2.3, 77]]`. The latter can be useful for directly loading into a map: `new Map([[1.2, 44], [2.3, 77]])` will create a map `{ 1.2 → 44, 2.3 → 77 }` and would 1. preserve the type of the keys (they'd be numbers) 2. preserve the insertion order. – VLAZ Apr 26 '21 at 09:17
