Nikolai,
"What is the easiest way to make a string "LikeThis" --> "likeThis"?"
Te easiest is not always the best.
The code should be correct and reasonably efficient. For example,
func firstToLower(s string) string {
if len(s) > 0 {
r, size := utf8.DecodeRuneInString(s)
if r != utf8.RuneError || size > 1 {
lo := unicode.ToLower(r)
if lo != r {
s = string(lo) + s[size:]
}
}
}
return s
}
$ go test tolow_test.go -bench=.
