How to learn Golang?

[G1K777]

Hello,

this question might seem bit stupid but I'm dead serious with it.

To write a simple "Hello World!" in Go is simpler than doing this in NodeJS (Because NodeJS has a trash setup).

 

package main

import "fmt"

func main(){
  fmt.Println("Hello World")
}

Very simple right?

Each Youtube video about Golang I've seen kind helps but not really. All you hear "do this, this is for that.." but not in the Docs nor in any Youtube video have they explained the basics.

I mean how do you write variables in other languages?
 

// JS
var varName = 5;
let varName = 5;
const varName = 5;

// or

var varName1 = 5,
    varName2 = 6,
    varName3 = 7; //etc. Works same with const and let.

With PHP it's also easy, $variableName and it's done.

 

But in Golang I saw no one explaining this:
 

something := 5 // <-- talking about this.
var otherSomething int = 5

Luck that there is something like w3schools, MDN that makes everything really easy but where the heck do I learn the fundamentals of Golang?

All I want to do, is getting a webhost working on my PC. That's all.
The issue is, my browser (chrome) is loading the index.html but how do I load the CSS and JS?

 

I'm siting since 35-40h (in total, sleeping and breakes not included) googling Golang, the whole time. I'm kinda pissed how you can tell, who wouldn't be? It took me 1 day to run NodeJS without using express and make my website run on it.

With Golang I'm sitting here and i know nothing, the docs don't give you a starting point at all. They teach me how to make a gowiki where the content is loaded from txt files ? Like you seruous, txt files?

 

This is what i have now and don't ask me how it works.

package main

import (
    "io/ioutil"
    "net/http"
)

type MyHandler struct {
    http.Handler
}

func (this *MyHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
    path := "public/index.html" // + req.URL.Path
    data, err := ioutil.ReadFile(string(path))

    if err == nil {
        w.Write(data)
    } else {
        w.WriteHeader(404)
        w.Write([]byte("404 - " + http.StatusText(404)))
    }
}

func main() {
    http.Handle("/", new(MyHandler))
    http.ListenAndServe(":3000", nil)
}

I never coded anything in Python, Delphi, any C language.

It's not much more than just a list of things, but does cover the fundamentals such as variables and the likes. Haven't worked in Golang myself though.
