Using the useParams Hook in React

I'm assuming you're using react router, if you define a route like this for example:

<Route path="/:id/about">
 <About />
</Route>

Notice that you define the path with this :id notation, that means that the id will be the param in this specific case. Then you create a Link component

<Link to="/2/about">About</Link>

And in your component that in this example is the about component you can use the hook like this:

function About() {
 const { id } = useParams();
 return (
  <div>
   <h2>Now showing post {id}</h2>
  </div>
 );
}

I have this code sandbox if you want to check the result

Assuming you are using react-router, then you should use Browser Router in your React app:

and then declare a route like:

<Route path="/{id}/solution" component={Component} />

and then in your Component you'll be able to use it:

const { id } = useParams();
