How to make commands with "similar" text?

Question

Node.js

There is a command: "help"
How can I make it run on "hrlp" as well, but without adding every possible error to execution?

Answer 1

If the set of possible commands is small, then the Levenshtein distance will suit you, with which command the distance is minimal - that is what the user meant, well, it’s worth keeping a certain threshold value, if all commands are “further” than this value, then nonsense has been introduced
