"React Routing In-depth Video Tutorial" This tutorial is about React routing in more than 20 minutes. When it comes to routing, the first thing that comes to mind is the routing system in ASPNET MVC - by defining a set of routing rules in advance, the program can automatically follow the rules when running. The URL we enter returns the corresponding page. The routing in the front-end is similar. The routing in the front-end renders different pages/components according to the routing rules you define, and also updates the URL in the address bar.
