REPL Driven Design

Read Original

The author details their experience using REPL Driven Design while building a Clojure program to process COVID-19 statistics from Johns Hopkins data. They describe the speed and satisfaction of the REPL workflow but later encountered fear and a bug when a design change was needed, realizing TDD would have enforced a more decoupled, testable design from the start.
