Question
Consider the following React Code. What will be the output when we go to route “/dogs/1”?function App() { return ( <div className="App"> <Switch> <Route exact path="/" component={Home} /> <Route path="/:animal" exact component={Animal} /> <Route path="/:animal/:id" exact component={Animal} /> </Switch> </div> );}function Animal() { let params = useParams(); return ( <div> <div>{params.animal}</div> <div>{params.id ? params.id : 0}</div> </div> );}Adogs0Bdogs1Cno-animal0DHome Component will be rendered
Solution
The output will be "Bdogs1". When we go to the route "/dogs/1", the Animal component will be rendered because the path matches the "/:animal/:id" route. The useParams() hook will extract the parameters from the URL, so params.animal will be "dogs" and params.id will be "1".
