I mean, the title is kind of link-baity. But the article even answers the question:

"What about type inference, traits, vals, implicits, case classes, value classes, static objects, pattern matching, type variance, macros, immutable datatypes, lazy vals, existential types, higher-kinded types, type classes."

Agreed, Why Java 8 is actually good for Scala (or even Java Folks, Welcome to Planet Lambda!) would have made a better (though less link-baity) title

If you're like me, who uses a lot of Java but hasn't learned Scala, then - no, it's not so obvious. The title was exactly a question I suppose I had.
