Yeah in Typescript I rarely run into null deference errors at runtime either. It can happen if you unsafely cast the type of values coming into your code, but if you runtime validate input at your application boundary it’s very unlikely
Now looking back at a lot of other languages that don’t express nullability, it’s like, what were they thinking? How did I not wish for nullability in type declarations in all my years of dealing with NullPointerExceptions?
