Introduction

In the previous chapter, we learned about sequences in Clojure and how working with them helps us to build Clojure programs. Now that you're familiar with using Clojure to implement various pieces of functionality, it's time to become more comfortable with accomplishing the basic tasks of creating, building, testing, deploying, and running projects in Clojure and ClojureScript.

Clojure was designed to be a very practical language from the beginning. Getting things done means interacting with the outside world, building projects, using libraries, and deploying your work. As a developer, you will need to organize written code in a structure. In this chapter, you will see how namespaces can help you structure code and how build tools such as Leiningen help you put together a whole application.

In a real-world project, you won't write all the code. External dependencies are a crucial part of any project, and we'll learn here how to bring them into...
