TDD Todo workflow kata (~1 hour)

Write the tests that will use your app. Write your logic first with TDD. Do the UI later.

Currently, there is a failing test in Todo.test.ts for you to start by writing production code.

Hint: We need a class in ./src/api/Todo.ts made and imported into ./src/api/Todo.test.ts.

Next up

Clone/Fork and finish the logic writing your tests first.
