How do I convert a string to a lower case representation?

If you happen to be too lazy to click through to the strings package, here's example code:

strings.ToLower("Hello, WoRLd") // => "hello, world"

If you need to handle a Unicode Special Case like Azeri or Turkish, you can use ToLowerSpecial:

strings.ToLowerSpecial(unicode.TurkishCase, "Hello, WoRLd") // => "hello, world"

Yes there is, check the strings package.

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Println(strings.ToLower("Gopher"))
}
