Tour of Go 2.0

Functions continued

When consecutive parameters share a type, you can drop the type from all but the last. It’s a small shortcut, but you’ll see it often.

Here we shortened:

x int, y int

to:

x, y int
main.go ▶ Run in Playground 
package main

import "fmt"

func add(x, y int) int {
	return x + y
}

func main() {
	fmt.Println(add(42, 13))
}
