I'm sure there is a better way of doing this...

Welcome to Dev.to!
Not trying to discourage you or anything like that but I think you may get better assistance if you share your code on a website devoted to peer review. Perhaps this one: codereview.stackexchange.com Or if you have some specific idea about what you think could be improved, perhaps you could tell us and we can offer suggestions to you.
Thanks.
