Think higher level, write grounded code. Everything you need to know to write Scala with Cats

What the F[_]?!

We Scala programmers love abstractions and Cats is one of the most popular libraries. At the same time, Cats is notorious for having a steep learning curve. Functors, Applicatives, Semigroupals, not to mention the M word. Few people make sense of them all. For the rest of us mortals, it's a brick wall. Certainly was for me when I started.

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.

This course is for you if:
you want to get started with the Typelevel ecosystem
you want to learn Cats but found it confusing, abstract or obscure
you want to learn the more general category theory while being pragmatic
you want some practice material on Cats
you want to hear the Rock the JVM tune again at the end of the videos
Here are the skills you'll get:
you'll write correct code quicker and more concisely
you'll be able to read the concise code of other people MUCH more easily
you'll be able to motivate WHY you chose a particular type class or approach
you'll start to think in general terms naturally, or get better at it
you'll deeply internalize how to use type classes well in Scala
you'll manipulate data in a purely functional way EVERYWHERE
you'll be VERY intimate with the M word (to not let your mind wander, that's monads)
you'll instantly get more experience with Cats in 10 hours here than most Cats programmers in their first few months
you'll understand and use abstract math with purely pragmatic goals like calling an endpoint or sending an email
Here's how you'll get them:
we'll have structure and logical progression, instead of you being thrown in the pool
we'll write code 98% of the time - we have 2k LOC on camera
we'll practice the S[_] out of everything - we have dozens of exercises and examples
we'll see/speak no boring abstract math
we'll deconstruct things that otherwise seem really obscure
we'll talk everything on Slack if there's anything confusing
we'll share all the code, slides and cheat sheets
After this course, you'll be able to read and write any code, however complex, that has Scala with Cats in it.
