Week 1 · Launch your environment
- Install Node.js 22.20 LTS and pnpm globally.
- Open VS Code with your bootcamp folder so nothing feels hidden.
- Double-check your setup with quick version checks for Node and pnpm.
Weeks 1–2 Highlights
Catch up on the first two lessons and see what skills you’ll practice next.
Week 2 · Variables & types
- Use const and let intentionally while practicing reassignment rules.
- Recognize everyday primitives and when to add explicit annotations.
- Compare inferred versus explicit types before running your code.
Build confidence with functions
- Write calculator helpers with typed parameters and return values.
- Predict TypeScript errors before they appear in the terminal.
- Validate command-line input so your scripts fail safely.
