Sort JavaScript map by decimal key

I have a map with keys as months and key values as 1...31. If I understand correctly, JavaScript converts the map's keys to strings. After sorting using standard newMap([...myMap.entries()].sort()), the map is sorted by key as follows: 1,11,12,13,...,19,2,20,21,22 ,23,...29,3,30,31. I found a way ...

I am a newbie who has just studied for 3 days. I want to ask some questions about my studies.

I was typing the code I learned, but the results I got were somewhat different from what I learned. The sorting method is sort(), but when I typed it, it turned out that it was not queued. I hope you can help me with the answer.
