Agreed. This course (my first into to functional programming) makes it hard to go back to working in Java. Things that can take a lot of code, such as grouping, filtering and aggregating data, can usually be achieved very naturally and concisely in Scala.

Oh, Java is just excruciating to use after learning functional programming.

On the other hand, I don't know if you use Javascript much, but you'll see it in a very different (much better) light after taking a FP course.
