 So for me, or not for me, for everybody, there's a hook called use state. And it, it returns back two things. It returns back whatever the object is that comes, that you, that you define. So counter. And then it returns a method that is essentially the callback that says, here's the thing you're going to use to change that state property. So generally that the pattern is, if I have a state value called counter, then the method is going to be called set counter. And it takes one parameter in, it's just, it's a number. You can initialize a lot of stuff. So that now when I want to go through and change the state, I don't have to worry about what the previous value was because I can just say this dot, or it's not this, I can say set counter and then say counter plus one as the parameter going in. I don't have to worry about the previous state because it's just a, it's like a public member, a class based member.
