Uncle Bob did it again. Some months ago he wrote Type Wars, a post to defend static type systems are not really needed if you do TDD. Now he’s back. In his latest post, The Dark Path (I know: these titles sound like Star Wars sequels) he brings new weapons for the dynamic languages enthusiasts (argument from authority included) to tell everyone else all these static type checks are useless.
In his new article, Bob tells he has been in the playground with Swift and Kotlin. And he didn’t like the experience. In his own opinion, these languages are going too far (or too deep) introducing strongly typing features. And (guess what?)… who needs such strong typing when you have TDD?
After Type Wars, I wrote my own post explaining why Uncle Bob was wrong. And I feel the irresistible need to reason why he’s wrong again.
