Learning Go: Using sync package to handle concurrent write issues

We start of with a simple example: Iterate through and increment the value of the key

	counter := make(map[string]int)
	count := 1000

	for i := 0; i < count; i++ {
		counter["key"]++
	}

Learning Go: Return REST Response from struct/slice to JSON

We have a very simple REST server setup and access it via a GET request on http://localhost:8080/: \

func homeHandler(w http.ResponseWriter, r *http.Request) {
	fmt.Println("[homeHandler]")
	fmt.Fprintf(w, "Hello World")
}
