What is Cats Effect?
Cats Effect is a Scala library that allows us to write composable and high-performance applications with pure functional programming.
What?!
Cats Effect comes with a powerful tool called the IO monad, which gives us the power to compose any kind of actions, aka “effects”. Besides that, we get great support for concurrency, parallelism and coordination, all with a strongly typed system (it’s Scala of course).
On more general terms, Cats Effect comes with a group of abstractions that make clear distinctions between different kinds of effects, so we can write more composable code.
The end result is more expressive power, higher performance, fewer bugs, less boilerplate, and most importantly, more happiness and productivity for us as Scala engineers.
This is what you’ll learn in this course.
How This Course Works
How this Cats Effect course works
Two words: writing code.
This course is as hands-on as you can get. We learn everything from first principles, not assuming any pre-existing Cats Effect experience, and we build up from there. We discover what effects are, how we can use them, how to compose code, how to design parallel and concurrent applications and how to generalize and make the code modular, all through practical examples. We write 3000 lines of code from scratch.
In this course, we have both theory and practice, so you can not only learn Cats Effect as a tool, but you internalize timeless principles for pure functional programming and high-performance applications.
The course was specifically designed to give you a smooth learning curve by deconstructing Cats Effect and sequencing the topics carefully. Nothing too steep or too boring.
In this Cats Effect course, we go from practice to theory, until pure functional programming gets deep in your bones as a Scala developer.
This course is 100% compatible with Scala 2 and Scala 3.

My team is expanding the use of Akka in our products so I needed a quick introduction on this topic. I have tried a couple of courses but the introduction to Akka was always too abrupt, too hard to comprehend. I blamed Akka for this as being too hard to explain. This was until I was exposed to the Rock The JVM courses which were an absolute delight when it comes to presenting such complex topics in such an easy to understand way. And Daniel has not stopped at Akka but has added to his portfolio amazing courses on Scala and Spark too. It seems like he is quite enjoying taking such challenges like complex technologies and making them so simple for everyone. I have instantly recommended Daniel’s work to my team, which helped them immensely with taking their skills to a new level, and I do recommend these courses to anyone who wants to have the fastest ramp-up in these tough but popular technologies.

From Scala, to Akka, to Spark, Daniel delivers exceptional material in each and every one of these technologies. I’ve been using them for a long time and there is always something new I will discover from him. The level of detail he gets into as well as the way he delivers material is mindblowing. I personally find his latest course Spark Optimization pure gold and one of a kind. I’ve been using Spark for a year now and I haven’t even thought how much you can leverage query plans to make such optimizations. I can’t stop thinking every time, how he manages to go so deep - because using a technology is one thing, but knowing its internals so well and how everything works behind the scenes is another story when it comes to distributed systems. Long story short Daniel is definitely the best instructor I’ve come across and each one of his courses is the best resource you can find online. Kudos for all your work and knowledge sharing.

Daniel’s courses on Scala and Big Data are the best in class. I’ve been in touch with Daniel’s teaching and courses since early 2018. The first course that I took from him was Scala & Functional Programming; I was skeptical about it because over the internet there are many courses you can find, but few really worthy. I remember the very first day when Daniel started to speak and shared his examples - I started to love Scala, and then more as we went on. I am with Scala for the last 5 years now, but never ever has anyone explained to me or gave me comparable resources to Rock the JVM. Daniel gave me a shift in life and helped me crack top tech company interviews. His courses on big data are a must for any aspiring big data developer or data enthusiast. I highly recommend Daniel as an educator both online and on campus.

Meet Rock the JVM
Daniel Ciocîrlan
Founder, Rock the JVM
I'm a software engineer and the founder of Rock the JVM.
I started Rock the JVM out of love for Scala and the technologies it powers. They are amazing tools, and I want to share as much of my experience with them as I can.
I've taught Java, Scala, Kotlin and related technologies such as Cats, ZIO and Spark to 100,000+ students at various levels. I've held live training sessions for companies including Adobe and Apple, taught university students who now work at Google and Facebook, run Hour of Code for 7-year-olds, and taught more than 50,000+ kids to code.
I have a Master's Degree in Computer Science and I wrote my Bachelor and Master thesis on Quantum Computation. Before learning programming, I won medals at international Physics competitions.
