How to reverse a string in Go?

Question

How can we reverse a simple string in Go?

Answer 1

It's assuredly not the most memory efficient solution, but for a "simple" UTF-8 safe solution the following will get the job done and not break runes.

It's in my opinion the most readable and understandable on the page.

func reverseStr(str string) (out string) {
    for _, s := range str {
        out = string(s) + out
    }

    return
}
