What exactly is Dynamic Routing in ReactJS

Question

I have been all around internet about the dynamic routing of React. But I couldn't find anything which explains how it works and how it is different than static routing in every single sense.

I understood it pretty well how the things go when we want to render something in the same page using React-Route.

My question is how does it work when a whole new page is wanted to be rendered? Because in this case all the DOM inside that page has to be re-rendered. Thus would it be static routing? or still dynamic in some ways?

I hope I've been clear. Thanks for the answers in advance, I appreciate!

I don't think the above explanation is correct for Static vs Dynamic routing.Also there is not much explanation in the web for it, but there is a very nice explanation in React Router Docs.From the Docs

If you’ve used Rails, Express, Ember, Angular etc. you’ve used static routing. In these frameworks, you declare your routes as part of your app’s initialization before any rendering takes place. React Router pre-v4 was also static (mostly). Let’s take a look at how to configure routes in express:

In Static routing, the routes are declared and it imported in the Top level before rendering.

Whereas in Dynamic routing

When we say dynamic routing, we mean routing that takes place as your app is rendering, not in a configuration or convention outside of a running app.

So in Dynamic routing, the routing takes place as the App is rendering. The examples explained in the above answer are both for static routing.

For Dynamic routing it is more like

const App = () => (     <BrowserRouter>         {/* here's a div */}         <div>         {/* here's a Route */}         <Route path="/tacos" component={Tacos}/>         </div>     </BrowserRouter> )  // when the url matches `/tacos` this component renders const Tacos  = ({ match }) => (     // here's a nested div     <div>         {/* here's a nested Route,             match.url helps us make a relative path */}         <Route         path={match.url + '/carnitas'}         component={Carnitas}         />     </div> ) 

First in App component only one route is declared /tacos.When the user navigates to /tacos the Tacos component is mounted and there the next route is defined /carnitas.So when the user navigates to /tacos/carnitas, the Carnitas component is mounted and so on.

So here the routes are initialized dynamically.
