Wrapping Up

In this chapter we took a tour of clojure.spec, a Clojure library for verifying the shape of data.

Along with the basics, you now know enough about the features of Clojure that it’s time to start thinking beyond the language. So in the next part we’ll look at how you can use Clojure to interact with the wider world, a world where you need to call Java libraries and ...
