While this first Option/Some/None example doesn’t deal with null values, it’s a good way to demonstrate the Option/Some/None classes, so we’ll start with it. We’ll provide an introduction to the techniques in this lesson.
Scala’s solution is to use constructs like the Option/Some/None classes. That brings up an interesting question: In the situations where you might normally use a null value in Java/OOP code, what do you do?
Info: JavaScript is currently disabled, code tabs will still work,įunctional programming is like writing a series of algebraic equations, and because you don’t use null values in algebra, you don’t use null values in FP.
