TypeScript session two exercises

Material for the session

wunderdog.dev/presentations/advanced

Working with the exercises

The exercises are supplied as function stubs in src/session_two.ts which you are expected to fill in.

The function stubs are accompanied by tests in test/session_two.tests.ts. When a test set for a given function passes, an exercise has been completed.

Running the tests

npm install
npm run watch

Lint your code

npm run lint

Working with the exercises

Open the src/session_two.ts in an editor with TypeScript support (a recent version of VS Code is highly recommended), fill in the behavior to the function stubs and run the test set.

Note that Jest (the test runner) will not report type errors!

Focus on specific excercises by running the watch-command, press p, and write a filter, like get.

As long as there are failing tests, just keep repeating the process. Enjoy!
