docs: // Humanize returns the humanized form of a single parameter.
  //
  // If the parameter is either an integer or a string containing an integer
  // value, the behavior is to add the appropriate ordinal.
  //
  //     Example:  "my-first-post" -> "My first post"
  //     Example:  "103" -> "103rd"
  //     Example:  52 -> "52nd"
