⚡ Lab Format
Every lab is Docker-verified:
🎯 Objective — what you build and why it matters
📚 Background — language concepts and theory
🔬 Step-by-step — real code with 8+ hands-on steps
📸 Verified output — actual output from Docker containers
🚨 Common mistakes — language-specific gotchas
🔗 Further reading — official docs and resources
Prerequisites: Docker installed. Each language has its own pre-built container — no local language installation needed. All labs verified on Ubuntu 22.04.
