Go: basic looping

Loop.go

package main

import (
	"fmt"
)

func main() {
	fmt.Println("Hello, playground")
	
	for i:=0; i < 5; i++ {
		println(i)
	}
	
	// Like while loop
	k := 0
	for {
		k++;
		println(k);
		
		
		if k > 5 {
			break
		}
	}
	
	// Loop through collections arrays, slices, maps
	s := []string{"foo", "bar", "buz"}
	
	for idx, v := range s {
		println(idx, v)
	}
	
	// Loop through map
	m := make(map[string]string)
	m["first"] = "foo"
	m["second"] = "bar"
	m["third"] = "buz"
	
	for k, mv := range m {
		println(k, mv)
	}
	
	// Prints the size of map
	println(k)
	
	
}
