Go Unpacking Array As Arguments

Question

So in Python and Ruby there is the splat operator (*) for unpacking an array as arguments. In Javascript there is the .apply() function. Is there a way of unpacking an array/sli

Answer 1

You can use a vararg syntax similar to C:

package main
import "fmt"

func my_func( args ...int) int {
   sum := 0
   for _,v := range args {
      sum = sum + v
   }

   return sum;
}

func main() {
    arr := []int{2,4}
    sum := my_func(arr...)
    fmt.Println("Sum is ", sum)
}

Now you can sum as many things as you'd like. Notice the important ... after when you call the my_func function.
