Run Instructions

You can type-check any file with tsc using npx (no local setup required):

npx tsc --noEmit workbook/workbook.ts

To run a single topic file:

npx tsc --noEmit workbook/sections/01-introduction.ts

Tip: Uncomment the TODO exercises as you go. Type errors are expected while you are mid-exercise.
