What you'll build

A command-line todo app in plain JavaScript on Node.js — no frameworks, no third-party packages. node cli.js add "buy milk" appends a todo to a todos.json file; node cli.js list prints your todos as numbered rows. The todo logic lives in a small module you test with Node's built-in test runner.
