Nullable types (`int?`), the `default` keyword, and the null-forgiving operator (!) set the stage for creating powerful Monads like Optional and Either in Unity. In this video, we dive into how these Monads can eliminate null checks, handle success and failure scenarios, and simplify branching logic. With practical examples, you'll learn how to implement Optional and Either to write cleaner, safer, and more expressive code for your Unity projects.
