Question

Is there, in Go, a more idiomatic way to add all the elements of an array/slice into a channel than the following?

ch := make(chan string)
values := []string {"lol", "cat", "lolcat"}

go func() {
    for _,v := range values {
        ch <- v
    }
}()

I was looking for something like ch <- values... (which is rejected by the compiler)

You can declare a chan of string arrays, unless you absolutely want to keep a chan of strings :

package main

import "fmt"

func main() {
    ch := make(chan []string)
    values := []string{"lol", "cat", "lolcat"}

    go func() {
            ch <- values
    }()

    fmt.Printf("Values : %+v
", <-ch)
}
