We tend to code using patterns that we repeat a lot. Learning these patterns can help you level up your macro skills very quickly. This reference sheet contains six annotated patterns that Clojure programmers use all the time. Have you ever wondered what the symbols in Clojure macros do? I’m talking about `, ~, ~@, etc. This handy reference sheet tells you what they all do, when to use it, and shows examples. Never get lost in a macro again! When we’re developing macros, it really helps to be able to see what code it will output. Fortunately, Clojure comes with three built-in functions for doing just that. They are so useful for debugging. This reference sheet shows what each one does. It also includes how to access macroexpansion in the three most popular Clojure […] Want a handy reference for writing your tests?

Pragmatic and in-depth guides to a topic. Why building something useful to you is bad advice and 10 side projects you can do in a weekend. 5 functional programming ways to impress a hiring manager with your resume. Is functional programming a fad? We cut through the buzz cycle and answer the question once and for all. So you want to know who’s using Clojure and where to find jobs? You’ve come to the right place. Your Database is going to contain a lot of important information. When
you’re first starting out your app, you don’t know exactly what you’re
going to store in there. In addition, you don’t know how you’re going
to want to access it. Both of these will evolve over time as you
understand more of the domain and you uncover the complexities of your
UI. We want some help from the framework (Re-frame) to help us deal
with this evolution. Reagent is a ClojureScript wrapper around React. It makes it easy to create React components using functions and hiccup, and state managed in Atoms.10 Weekend projects to spruce up your Functional Programming resume

Video Courses
Screencasts, Whiteboards, and Slides produced to help you learn Learn these three tools — map, filter, and reduce– and you’ll be well on your way to developing a functional mindset. I get a lot of questions from people trying to learn Clojure. Sometimes, the best way to answer them is with a video. This course is for all of those questions that don’t really fit anywhere else. 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. Sometimes we want to see how individual components are built. We want to know how to reproduce common components easily using Re-frame. In this course, we take that approach. We build individual, interactive components, going through the design decisions we have to make. 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? Clojure is based on collections, but how are they used? What are some patterns for making the most of them? This course introduces you to the workhorses of the Clojure programming language, the immutable collections.3 Functional Tools

Parts of courses on specific topics Now that we have an efficient way of fetching ingredients, let’s handle the orders for the day. Do you understand the pattern of using helper functions within a macro and how it can make your macro more useful and easier to understand? This lesson teaches how to read in JSON and explore data. This lesson includes a video screencast. The screencast is 25 minutes long. Sometimes we need to get a reference to the real DOM node that React normally manages for us. For instance, when we need to play an embedded video, the API requires access to the DOM node of the video element. React gives us a feature called Refs that let us get access to any DOM node it creates. You know those HTML components that show you some headers and let you expand the content underneath? Yeah! Let’s build one! Let’s add a new ingredient, namely cocoa.A day at the bakery

Down on React? You should check it out from the ClojureScript perspective. How is it possible that Clojure is better than Java at its own game? Hear me out, then decide for yourself. Clojure was designed as a hosted language. So what is Clojure, the language, if it relies on the features of a host? And what are the disadvantages of choosing the JVM as a host? People know about the immutable data
structures and the STM. But there’s something going on at a much
deeper level that is really hard to get right in Java. It has to do
with the optimizations the JIT will run on your code. Many of us have to use JavaScript. But does that mean we can’t use functional programming? Sure, with discipline. But can we make it even easier? Clojure startup times suck. Let’s just be honest. How do Clojure programmers live with that? Maybe that’s the wrong way to think about it.6 things Reacters do that Re-framers avoid
