## How to Use
### JS files
Run with Node.js:
```bash
node 01-basics/00_variables.js
```
### HTML files
Open in a browser directly - no build tools required.
---
## Learning Path
1. **Start with basics** (00 → 16) in order - each file builds on earlier ones
2. **Move to DOM** - see JavaScript in the browser
3. **Tackle async** - the most critical skill for modern JS
See [docs/learning-roadmap.md](docs/learning-roadmap.md) for details.
---
## Philosophy
This repo documents learning in public. The code is deliberately:
- **Self-documenting** - minimal comments, meaningful names
- **Practical** - real patterns, not just syntax
- **Progressive** - each file builds on earlier concepts
- **Interactive** - HTML files are visual playgrounds
