  3. Documentation alongside code - Always current
  4. Type-first design - Fewer runtime errors
  5. Example-driven APIs - Validated ergonomics
  6. Parallel implementation - Multiple features simultaneously

Challenges Overcome 💪

  1. Clippy warnings - Fixed with auto-fix and manual edits
  2. TypeScript test mocks - Corrected API response format
  3. Formatting consistency - Applied cargo fmt across all files
  4. CI pipeline - Resolved all check failures

Best Practices Reinforced 💡

  • Write tests before implementation
  • Document public APIs immediately
