The problem here is that split returns [""] when called on an empty string, and the length of that array is indeed 1. To counteract this, you can replace the {text.split(" ").length} part of your code with {text.trim() === '' ? 0 : text.split(" ").length} so that the case where the input is only whitespace is taken care of.
