If this was an array anybody could get the infexOf any character they want.

True but that wouldn't be as efficient as an O(1) lookup as is the case with an object. I used the above in a leetcode problem so time complexity was a concern.

in what case would you need to get the indexOf a character if your using an object anyways?

Plenty of string problems on Leetcode has this need. Although for most it would be starting at 1 not 0 like the original snippet I posted. Anyway since then I found a easier way to do this:

// If you need to map alphabets to their corresponding index
"a".charCodeAt() - 96; // 1
"z".charCodeAt() - 96; // 26

Go

	letters := []string{} // or []rune{}
