Golang: title casing first character only

Technically I think title case means all major words have their first letter capitalised.

This isn’t that; its capitalising the first work only.

I use this when rendering error fields to users. I like to keep all my errors consistent and lower cased. This means some extra work when presenting errors to users, for instance form field errors.

package main

import (

func WithTitleCase(s string) string {
	return strings.ToUpper(s[:1]) + s[1:]

func main() {
	sentance := "today was a good day"
	newSentance := WithTitleCase(sentance)
