Advice generator app (w/ typewriter + die spin animation)

Any feedback appreciated!

There's a bug where generating a new advice slip while a typewriter animation is still ongoing causes the new message to write out twice as quickly. I believe it's because of multiple typewriter functions running asynchronously because of setTimeout(), but I don't know how to fix it without also forcing the user to wait until the typewriter animation fully completes. Any tips for how to resolve this issue would be greatly appreciated!
