In this section, we're going to see how to create a simple file server. The main idea behind a file server is to serve static files, such as images, or CSS files, or JavaScript files, and, in our code, we're going to see how to do this. Check the following code:
package main
import "net/http"

So, what's going to happen is that when the request hits the route path, a file server will serve the requests and it will give static files under the location http.Dir("./images"). We are going to use http...
