function truncate(
  str: string,
  maxLength: number,
  fill: string = "...",
  style: "leading" | "trailing" | "middle" = "trailing"

truncate("Hello World!", 4, "/") //=> "Hell/"

truncate("Hello World!", 4, "...", "leading") //=> "...rld!"

truncate("Hello World!", 4, "...", "middle") //=> "He...d!"
