A custom Hook, unlike a React component, does not require a signature. We may choose what it accepts as parameters and what it should return, if anything. To put it another way, it's just like any other function.
In react router v5, we can use the useParams() hook to grab the url parameter from a current route. Consider the fact that we have a route similar to this in our react app. Using the useParams() hook, we can now retrieve the:id param value from a Users component. You may use props.match.params.id in React router v4 to get to it.
