Deep in your innermost being, you’ve always known you were destined to learn Clojure. Every time you held your keyboard aloft, crying out in anguish over an incomprehensible class hierarchy; every time you lay awake at night, disturbing your loved ones with sobs over a mutation-induced heisenbug; every time a race condition caused you to pull out more of your ever-dwindling hair, some secret part

One day, while you are walking down the street, you will be surprised, intrigued, and a little disgusted to discover a hot dog vending machine. Your scalp tingling with guilty curiosity, you won’t be able to help yourself from pulling out three dollars and seeing if this contraption actually works. After accepting your money with a click and a whir, it pops out a fresh hot dog, bun and all. The ve

So far, you’ve focused on becoming familiar with the tools that Clojure provides: immutable data structures, functions, abstractions, and so on. In this chapter, you’ll learn how to think about your programming tasks in a way that makes the best use of those tools. You’ll begin integrating your experience into a new functional programming mindset. The core concepts you’ll learn include: what pure

On your journey to Clojure mastery, your editor will be your closest ally. I highly recommend working with Emacs, but you can, of course, use any editor you want. If you don’t follow the thorough Emacs instructions in this chapter, or if you choose to use a different editor, it’s worthwhile to at least invest some time in setting up your editor to work with a REPL. Two alternatives that I recommen

You learn Clojure here. Therefore, Brave Clojure is your very best friend when it comes to programming.” And lo, the syllogism was born! Do you want to learn Clojure, the most powerful and fun p
