Generic Go Function: Handling Strictly Different Argument Types

Simple example of a Go function that uses generics and takes a string or slice of strings as arguments.

foo("Hello, world")
foo([]string{"Hello, world", "こんにちは、世界"})

package main

import "fmt"

func main() {
	foo("Hello, world")
	foo([]string{"Hello, world", "こんにちは、世界"})
}

func foo[T string | []string](input T) {
	switch values := any(input).(type) {
	case []string:
		for _, value := range values {
			fmt.Println(value)
		}
	default:
		fmt.Println(values)
	}
}
