Array: Fixed Length list
Slice: An array that grow and shrink
Every single record must have the same type

package main

import "fmt"

func main() {
	cards := []string{"Ace of Diamond", newCard()}

	cards = append(cards, "Six of Spades")

	fmt.Println(cards)
}

func newCard() string {
	return "Five of Diamonds"
}

[]string : define a slice of type string
{"Ace of Diamond", newCard()}: initialize with values
append(cards, "Six of Spades"): append a new value to the slice and returns a new slice
Slices index start with 0
indexing: slice[0]
indexing: slices[startIndexIncluding: upToNotIncluding]
ignore the startIndexIncluding to start from start
ignore the upToNotIncluding to go till the end
