Example
- Like in Lisp
slice...syntax when you pass to a function
// Variadic functions can be called with any number of trailing arguments. For // example, fmt.Println is a common variadic function. // Run code // Here’s a function that will take an arbitrary number of ints as arguments. sum := func (nums ...int) { fmt.Print(nums, " ") total := 0 for _, num := range nums { total += num } fmt.Println(total) } // Variadic functions can be called in the usual way with individual arguments. sum(1, 2) sum(1, 2, 3) // If you already have multiple args in a slice, apply them to a variadic function using func(slice...) like this. nums := []int{1, 2, 3, 4} sum(nums...)
[1 2] 3 [1 2 3] 6 [1 2 3 4] 10
