	// standard for loop
	for i := 0; i < 10; i++ {
		fmt.Println(i)
	}

	// while loop
	j := 0

	for j < 10 {
		fmt.Println(j)
		j++
	}

	// Infinite loop
	i := 0

	for {
		fmt.Println(i)
		i++

		if i > 10 {
			break
		}
	}

	// loop over a slice
	numbers := []int{1, 2, 3, 4, 5}

	for i, n := range numbers {
		fmt.Println(i, n)
	}

	// loop over a map
	colors := map[string]string{"red": "#ff0000", "green": "#00ff00", "blue": "#0000ff"}

	for key, value := range colors {
		println(key, value)
