In react. Routing settings, how to make a page component display by default?

in vue, vue-router I redirect with redireact, and the route jumps to that specified route, and the page component is displayed. When I use react, it doesn"t seem to show by default when it is set up in the route. Why is that?

I hope the great gods will solve their doubts!

there is also a component called Redirect in react-router .

as a reminder, it's best not to learn the analogy between react and vue .
