Cats

But it doesn't have to be. After lots of pain, I understood how this library can be fun to learn AND write with, IF - and that's a big if - you follow a clear structure and a smooth sequence. The bad news is that's tough to make. The good news is that I think (there's a good chance that) you have it in front of you.

You're looking at the only course on the web that doesn't cost an arm and a leg (and a real cat) and will get you through everything you need to know to be productive. Down to earth, hands-on, no psychobabble, and no F[_] bombs until you're ready.

This course is for Scala engineers at least at the level of the Advanced Scala course. By the end of this course, you'll be able to use any Cats feature without any problems.
