You’ve heard that Clojure is great for concurrency. But what tools does Clojure give you? And how should you use those tools?
These lessons are meant to each answer a specific question and help you build the skills you need to address a wide variety of concurrency problems.
Clojure core.async provides basic building blocks for communication and coordination. This course explores ten patterns you can easily implement using those building blocks.
With so many data formats out there, it’s good to see some example code for reading and writing different formats. I’m talking JSON, CSV, EDN, and more. This course explores how to read and write data formats using Clojure.
In Clojure, the common advice is “just use a map”. There’s some truth to that, but it’s obviously more complicated. Clojure gives you lots of ways to model a problem. In this course, I give you a peek behind the curtain. I work step-by-step through different iterations of a domain model, discussing what I’m thinking, why I’m trying something else. We model the game of solitaire, a card game we’re all familiar with.
Ever wonder how to read those destructuring forms? Do you want to know how to make your code clearer and shorter? Where can destructuring be used? And how do you construct each one? This course starts from the basics and works through all of the destructuring forms, ending with some examples and advice for using them.
Pragmatic and in-depth guides to a topic.
We look at a sequence diagram to organize the parts of Re-frame.
Learn the 4 React Lifecycle Methods you’ll need to know for Reagent/Re-frame and why the other 6 are not needed.
Re-frame gives us several places to put our state. So how do we choose? It turns out the decision is easy.
Find out the two types of jobs that tell you how much you need to learn to be hirable.
The Java ecosystem is big and it can be daunting. But fear not! You don’t need to learn everything, and once you learn enough, it will be worth it. You will realize that it is not so intimidating. This guide will be your . . . guide.
Re-frame adds a beneficial amount of structure to your frontend app. This guide goes over all of the pieces of that structure and how to use them.
There are several features of Java that generate weird classnames. We look at how to refer to them from Clojure.
There are many reasons to learn Functional Programming. I go over my 11 favorite reasons. Reason #1 is it’s fun!
I had to choose between Re-frame and Om Next when building a course. Here are the reasons why.
Clojure error messages and stacktraces are the number one most complained-about feature of Clojure. We look at some tips and resources for dealing with them.
Parts of courses on specific topics
Flow is a mental state where we feel totally immersed in our activity. We feel deep enjoyment and are energized by it. It’s the state the repl-driven programming promises us.
In this lesson, we look at Flow, its benefits, and what is needed to maintain it.
Let’s take a look at the `day-at-the-bakery` function and see how we can improve it.
We make note of some duplication and make a plan for removing it.
If you’re curious about how the Leiningen project we used was created, I walk through the steps of creating a new project and setting up the bakery dependency.
Applicative functor is the topic of this video. It is a type of Functor that is extended to let you apply a functor of functions to a functor of its arguments.
This lesson teaches what apply does, how you can implement it, and when you’d want to use it. This lesson includes a video screencast. The video is 6 minutes long.

A one-page sheet with the basics for creating Reagent components for use with Re-frame. Get started with Re-frame right away.
If you program the web in Clojure, you probably use Ring. Even if you don鈥檛, your server is likely聽Ring compatible. Ring has a small SPEC. It鈥檚 centered around defining the keys one can expect in the request and response maps. And the exact names for keywords are easy to forget. I don鈥檛 want to forget. […]
