HTTP/2, full json support and a great networking stack, all that is part of Go’s standard library. Just like everything else you need for a smashing web application. You will learn the basics of web development with Go very hands on and with just the standard library of Go. By then building a REST API or simple server rendered frontend is a piece of cake. And let us not forget to properly test the bastard, before putting it out in the wild.
