无法打印完整的字符串数组

I'm trying to return a string array from a function, but it is printing only the last index position value. Here is my code and output.

package main

import (
    "fmt"
)

func main() {

    myquote := varFunc("Go", "Bunny", "Let's", "Change", "ourself")
    fmt.Println("here also:", myquote)

}

func varFunc(s ...string) string {

    fmt.Println(s)

    fmt.Printf("%T
", s)
    quote := ""
    for _, v := range s {

        quote = v
        fmt.Println("init: ", quote)
    }
    fmt.Println("is there: ", quote)
    return quote

}

Playground: https://play.golang.org/p/jyZDL5oPmcz

My output:

[Go Bunny Let's Change ourself]
[]string
init:  Go
init:  Bunny
init:  Let's
init:  Change
init:  ourself
is there:  ourself
here also: ourself

Program exited.

    Your code returns last value of quote which is the value on last iteration on string array s.

    If you need to return string array s - return it. Excuse me for truism.

    func varFunc(s ...string) []string {
    
        fmt.Println(s)
    
        fmt.Printf("%T
    ", s)
        quote := ""
        for _, v := range s {
    
            quote = v
            fmt.Println("init: ", quote)
        }
        fmt.Println("is there: ", quote)
        return s
    
    }
