> OK, then you know about currying, immutable data structures, map/reduce/filter, &c.

It's not a certainty you learn about those things from Java, depends on your team/manager/codebase. None of that is enforced in Java the way it is in fp. Plus, none of it is really core or native to Java, it was added on later.

That's how we got essays back in the 2000s like "The Perils of Java Schools", "Can Your Language Do This", and "Beating the Averages".
