I'm new in development. Now trying to learn gorilla/mux router. The question is about reversed urls. In gorilla/mux I know we name them with .Name() method and access with .Url(). Could someone explain real use case of reserved URL's(Reverse mapping URL)? But a few hours of googling didn't help me to find any info about that why we even need them? Will be really thankfull if you could show some practical examples.

What is your definition of "reversed URLs"? - Emile Pels
reserved URL or Reverse mapping URL - Farhad Kocharli
Below section is from gorila/mux doc.why we need and when use it? Now let's see how to build registered URLs.Routes can be named.All routes that define a name can have their URLs built, or "reversed".We define a name calling Name() on a route.For example: r := mux.NewRouter() r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler). Name("article") To build a URL, get the route and call the URL() method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: url, err := r.Get("article").URL("category", "technology", "id", "42") - Farhad Kocharli

Use cases if someone needs.

• Constructing redirects to send to a client - eg programmatically, so you don’t have to fix the URLs in your code elsewhere

• Building examples & tests

• Generating docs
