// note - arrays are of FIXED size, while slices can be modified

////////// MAPS --- probably most used as we can use a string as an index instead of just integers
newmap := make(map[string]string) // make a map of STRINGS
newmap["lomas"] = "bbq"
newmap["horse"] = "handsome"
fmt.Println(newmap)

delete(newmap("horse")


/////////// slices 

// init slice
var slice = make([]string, 2) // make an array with 2 elements (0 and 1)

// add item to slice
slice[0] = "how are you?"

// append or add an item to slice
slice = append(slice, "how are you?")

// append multiple items
slice = append(array, "how", "are", "you", "?")

// delete item 2 from slice
slice = append(slice[:2], slice[2+1:]...) // note, only change the 2

// copy element to another slice
newslice := make([]string, 3) // this must be big enough to fit all the elements in
copy(newslice, slice)

fmt.Println(newslice)



/////////// arrays - only used if we know the size, we cannot change it once initialised

// init array
var array [2]string // make an array of strings with 2 items (0 and 1)

// add items to array
array[0] = "how are you?"

// output array OR slice
fmt.Println(array) // dump whole array
fmt.Print(array[0]) // output single item
