Just to clarify, if you update toReadableNumber to take a second parameter and that parameter is not a number, typescript will complain.*

TypeScript won't catch the original landmine because it ignores the extra parameters; maybe some linter would? Is there a rule that enforces "functions used by map must spell out all the parameters?"
