This lesson shows an in-depth example of repl-driven development. We start a new project to parse and analyze an unknown CSV file. By taking small steps at the REPL, we develop a program to parse the CSV. We test each step at the repl before moving on, and interactively expand the program. At the end, we have a program to parse it, and we have tested everything carefully along the way.
