Prerequisites

Before starting this track:

• Complete TypeScript Practitioner (labs 01-15)

• Comfortable with generics, decorators, async/await

• Understanding of npm packages and module systems

Docker Verification

All labs include Docker-verified code examples:

docker run -it --rm node:20-alpine sh

Each lab's code is tested and confirmed working in a clean Docker environment.
