Cats

• 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

• 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

• 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.
