How do I reverse the sequence of an object with numeric keys?

Question

Suppose there is an object in a JavaScript

let object = {
    "1": {"SUBJECT": "APPLE"},
    "2": {"SUBJECT": "BANANA"}
};

Which is equivalent to a dictionary in Python. Now if I wanted this: -

object2 = {
    "2": {"SUBJECT": "BANANA"},
    "1": {"SUBJECT": "APPLE"}
}

How do I get it?

@Pipe see the link from evolutionxbox - the short answer is "sort of yes" but it's also a bad idea to rely on it. — VLAZ

@BroteenDas that would do nothing. Object keys that are integers will be sorted first and will be in ascending order. You cannot override that. You either need a different data structure (a Map will always preserve insertion order) or keep a list of the keys in the array, sort that as you wish and then walk through the array fetching the corresponding value from the object. — VLAZ

So I figured it out... I just stored the Object.keys(object) in a list... reversed it and then iterated through the keys to get the object values... that was hella easy than I thought it would be... but thanks anyway to all of you who responded, interacted or even clicked on my question...
