Create Dynamic UI with Roact

Greetings all.

I recently decided to dive into the world of Roact, and I’ve hit a… bump.

It is my understanding that roact makes dynamic UI easier, but I can’t seem to find out how you would do this.

For the example question I’m asking, how would you make a UI update when a players health changes using Roact.

I’m well aware of how you could do this not using Roact, but I don’t want to do a mix. All in or nothing is what I’m going for.
