What's the Difference Between `http.Handle` and `http.HandleFunc` in Go?

Clarifying the Distinction between http.Handle and http.HandleFunc

In Go's http package, two main functions are available for handling HTTP requests: http.Handle and http.HandleFunc. While their purpose is essentially the same, there's a subtle difference in how they're used.

http.Handle takes two arguments: a URL path as a string and a handler interface that implements the http.Handler interface. This handler can be a struct or a function that meets the ServerHTTP method signature of the http.Handler interface. The http.Handler interface allows you to customize the HTTP request handling logic.

On the other hand, http.HandleFunc is a convenient helper function that takes the same arguments as http.Handle but simplifies the task by automatically creating a http.HandlerFunc type. http.HandlerFunc is a type that implements the http.Handler interface and can directly accept a function as a handler.

To summarize, while both http.Handle and http.HandleFunc achieve the same goal of associating a URL path with a handler, http.HandleFunc provides a concise syntax when a simple function-based handler is sufficient. Therefore, http.HandleFunc is preferred for most common scenarios, while http.Handle gives you greater flexibility to define complex handlers through custom structs implementing the http.Handler interface.
