1. Copy-paste ready - All examples are runnable as-is
2. Tested and proven - Every example has been verified to work
3. Evidence-based - Examples show expected outputs and verification
4. Multiple ecosystems - Choose the one that matches your stack

1. Single source of truth - Constants defined once in typescript/shared/
2. Type safety - Shared types across all TypeScript examples
3. Consistent patterns - Each ecosystem follows its own idioms
4. Easy maintenance - Bun monorepo for TypeScript workspaces
