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

What the F[_]?!

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.

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 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 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.
