func main() {
	var slice = []int{1, 2, 3, 4, 5}
	var store = make([]int, 3)

	push := append(slice, 6, 7, 8, 9)
	copy(store, slice)

	fmt.Println("before append value", slice)
	fmt.Println("after append value", push)
	fmt.Println("render value all value exist", push[:])
	fmt.Println("render value after second value", push[2:])
	fmt.Println("render value before third index", push[:3])
	fmt.Println("render value start from zero and last value before second index", push[0:2])
	fmt.Println("merge slice value", store)
	fmt.Println("read size slice", len(slice))
	fmt.Println("read capacity slice", cap(slice))
}
