 Now let's see how we can hook into side effects happening with our component with the use effect hook. In this example, I'll add a new state property to indicate if the counter value is even or odd. It needs to change whenever the counter value is actually changing. Sure, I could have implemented this directly in the rendering of the component, but it's a simple example to show how side effects are gonna work. I'm gonna go back to my code, jump back up to the top and I'm gonna import in another hook called the use effect. And this is effectively a way for me to say, I wanna add a side effect for something to happen when another thing happens on the page. So in my example, what I'm gonna do is I'm gonna add in a new call here to use effect. And this is going to take in, it's gonna have a function that's gonna run, I want some code to run whenever this side effect runs.
