Things I Was Wrong About: Types
A lot of people in the comments are saying how they started off in Java, or C, and hated types, but eventually grew to love them.I started off in PHP. It was wild. Anything could be anything. Refactoring was a nightmare. Our codebase was littered with mystery variables like $hold, $hold1, and $holda, which were re-used all over the place. (Granted, this two other problems entirely orthogonal to types.)Then I got a job at a Java place. My god, it was beautiful. I could suddenly know what arguments functions were expecting, even if I hadn't seen them before. I could be instantly aware if I was trying to use the wrong variable somewhere, or pass in invalid data.It was as if someone lifted me out of a dank cellar where I had previously subsisted on whatever mushrooms the rats didn't deign to eat, into a brightly lit dining room full of steak and pastries.
