while setting map, lot of times we have to check if property doesn't exist it has to be 0 . Otherwise we do +1.
so instead of line 9 and 10 . Single line can do this :
map.set(c, (map.get(c) || 0) +1)

Thank you for the video. Can I ask what program you’re using to sketch/draw out the work?

❗CORRECTION: Space Complexity: O(1) because the maximum length of the map is 26 which is the length of the English alphabet.
