Ever been completely baffled by Wikipedia articles on Monads and Functors? Are you curious about what everybody is raving about, but can't find any good ways to learn it? It turns out that many of the ideas of category theory come almost directly from the real world. Wouldn't you like to understand how those concepts relate to the real world? These lessons will show you:
- How a pile of rocks is a Monoid.
- How a list of notecards is a Functor.
- How a bag of candy is a Monad.
- And more.
If you already work at a large company, you may want to find ways to introduce Clojure to your work. This guide presents 5 steps for bringing Clojure into your job.
What if you could learn Clojure step-by-step, starting from zero? Wouldn't it be great if someone could guide you through each step? What if each step helped you master the material before moving on to the next? And what if it was fun and interactive? Would you like that? I sure would!
Learn these three tools -- map, filter, and reduce-- and you'll be well on your way to developing a functional mindset.
What is recursion? How do you write recursive functions? Does it work with laziness? How is it different from a
for loop? All of these questions are answered, and more, using simple, clear examples. You'll never have fear of recursion again.
Are you wondering how to test your code? Would you like to use the most popular testing framework for Clojure? Do you want to know the correct conventions so that your tests work well in IDEs and continuous integration services? This course teaches all of that in a fun, interactive style.
Clojure sequences are lazy by default. That gives you big benefits like separation of concerns, but it also brings with it some gotchas. This course is mostly about exploring those gotchas--problems that can bite you if you're not ready for them--and techniques to work with each one. Being prepared is the best antidote to a bad bite. After dealing with the downsides, we explore the big benefits.
People talk a lot about using data to model things in Clojure. But how do you do that? This 9-part series explores many different ways to model systems in Clojure, including with various literal data structures, closures, and records. This is a serious exploration with tradeoffs discussed. Your math teacher would be proud: all work is shown so you see how everything is related.
Protocols are a very cool and very important feature in Clojure. They are a great way to build polymorphism into your software, including extending existing Java classes without modifying them.
What mysteries do Clojure macros hold? This course jumps right into macros with gusto. It starts with the key to understanding macros, takes you through the implementation of 6 progressively more complex macros, and finishes with the three reasons you need macros.
In this course, we develop the frontend of an app to help a scientist record her experiment notes. It's a lab notebook. The app is completely client-side. It uses ClojureScript and Om.
Clojure core.async provides basic building blocks for communication and coordination. This course explores ten patterns you can easily implement using those building blocks.
