 they did an update to their project where everything was now hooks based. And so I had to learn, I had to sit there and port everything in the modules over to hooks because that's what everybody was gonna be seeing when they started doing the modules. And I found that when I did that, I was able to delete a lot more code of stuff that I was writing before. Most specifically, it's around working with state. And so before, you know, like with React, if you wanna do something with state and you wanna update a state value, but you have to use the previous state value as one of the thing, one of the, in the calculation of the new state.
