Quickstart

Install PNPM

Because this course is so big we're using pnpm as the package manager. It's like npm, but results in fewer node_modules saved to disk.

Install pnpm globally.

Install Dependencies

# Installs all dependencies
pnpm install

# Starts the first exercise
pnpm run exercise 001

# Runs linting and tests on the solution
pnpm run solution 001

How to take the course

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

To take an exercise:

1. Go into *.problem
2. Run pnpm run exercise 001, where 001 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. You can see if your solution is better or worse than mine!

You can run pnpm run solution 001 to run the tests and typechecking on the solution.
