How to concatenate two slices in Go ?

Question

I'm trying to combine the slice [1, 2] and the slice [3, 4]. How can I do this in Go?

I tried:
append([]int{1,2}, []int{3,4})

but got:
cannot use []int literal (type []int) as type int in append

However, the documentation seems to indicate this is possible, what am I missing?
slice = append(slice, anotherSlice...)

Add dots after the second slice: append([]int{1,2}, []int{3,4}...) This is just like any other variadic function. package main import "fmt" func foo(is ...int) { for i := 0; i < len(is); i++ { fmt.Println(is[i]) } } func main() { foo([]int{9, 8, 7, 6, 5}...) } https://play.golang.org/p/WkUgiWAUXYn
