Clojure Brain Teasers: Exercise Your Mind

You know Clojure, but do you really understand it? You may know the mechanics and idioms, but what about the deeper, implicit concepts driving the design? Discover and explore the real Clojure, testing and supplementing your understanding of why this data-driven functional programming language works the way it does.

You'll start with the basic concepts such as numeric types, numeric promotion, and logical truth. But the backbone of Clojure is its focus on immutable data, centered around the Clojure collections. Learn about collection equality, polymorphism on nil, adding and finding elements in different collection types, and sorted collections. Explore Clojure's evaluation model, including the Clojure reader, quoting, evaluation, and macro expansion. Finally, learn about the core library functions like case, concat, for, partial, and the details of type hinting, vars, and destructuring. Understand the peculiarities of these functions and how to apply them to your advantage in future programs.

Use these new insights to build your own concise, expressive, and flexible code. Don't just use Clojure, master it.

Now available in beta from pragprog.com/titles/mmclobrain.
