Reading

• A semantic grep as a CLI tool with mgrep. This unlocks use cases involving “RAG”, at least for a prototyping phase involving Claude Code SDK https://elite-ai-assisted-coding.dev/p/boosting-claude-faster-clearer-code
• 2nd time I hear about this “Effect” framework Seems to be a strange but powerful thing https://www.youtube.com/watch?v=MHpf_XMz_aM.

Learning

• TypeScript Best Practices:
  • Avoid Non-Null Assertions (!) - use explicit guards or destructuring
  • “Parse, Don’t Validate”: Transform loose input into strict types at the boundary
  • Use Type Predicates (isNode(n)) instead of as Node[] for type safety
• React Patterns:
  • Controlled vs Uncontrolled: Start with Controlled for critical UI components
  • Animation Cleanup: Use onAnimationEnd instead of setTimeout to avoid magic numbers
• Refactoring Insights:
  • Key-based Reset pattern for robust state reset in controlled components
  • Layered Architecture: Domain (parsing), State (hook), and UI layers
  • Explicit State Clearing on validation failure (YAGNI on unused complexity)
