A map of the Repl-Driven Development territory
We take a look at an idealized model of the development process so that we can understand all of the places where we can make tools and practices to improve our development workflow.
Example of Repl-Driven Development
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.
