Correct way to initialize empty slice

Question

To declare an empty slice, with a non-fixed size, is it better to do:

mySlice1 := make([]int, 0)

or:

mySlice2 := []int{}
         


        

Answer 1

Empty slice and nil slice are initialized differently in Go:

var nilSlice []int 
emptySlice1 := make([]int, 0)
emptySlice2 := []int{}

fmt.Println(nilSlice == nil)    // true
fmt.Println(emptySlice1 == nil) // false
fmt.Println(emptySlice2 == nil) // false

As for all three slices, len and cap are 0.
