Video Walkthrough

I walked through the first few exercises on VSCode's live stream! The plan for these exercises is to develop them into a full workshop, and then bundle them into the full video course - Total TypeScript.

How to take the course

You'll notice that the course is split into exercises. Each exercise is split into a *.problem.ts and a *.solution.ts.

To take an exercise:

1. Go into *.problem.ts
2. Run yarn exercise 01, where 01 is the number of the exercise you're on.

The exercise script will run TypeScript typechecks and a test suite on the exercise.

This course encourages active, exploratory learning. In the video, I'll explain a problem, and you'll be asked to try to find a solution. To attempt a solution, you'll need to:

1. Check out TypeScript's docs
2. Try to find something that looks relevant.
3. Give it a go to see if it solves the problem.

You'll know if you've succeeded because the tests will pass.

If you succeed, or if you get stuck, unpause the video and check out the *.solution.ts. You can see if your solution is better or worse than mine!

You can run yarn solution 01 to run the tests and typechecking on the solution.
