1. Hello REPL!
Overview
In this chapter, we explain the basics of creating Clojure programs. We start by getting you familiar with the Read Eval Print Loop (REPL), where most of the experimentation happens when writing code. The REPL also allows you to explore code and documentation by yourself, so it is an excellent place to start. After the quick dive in the REPL, we describe in more detail how to read and understand simple Lisp and Clojure code, which syntax can sometimes appear unsettling. We then explore fundamental operators and functions in Clojure, which enable you to write and run simple Clojure programs or scripts.
By the end of this chapter, you will be able to use the REPL and work with functions in Clojure.
