- Cindy99 built a data analysis tool using TypeScript in a modular architecture with a Jupyter Notebook-style interface for visualizations
- TypeScript's static typing helps catch errors and improves maintainability; the modular structure promotes code reuse
- Key metrics: low complexity score (0.03), low code coverage (0.8%), solid maintainability index (0.75)
- Expanding the test suite would help ensure code robustness
- Decoupling components into focused, single-responsibility modules makes them easier to understand, reuse and modify
- Notebook-based approach is popular for exploratory data analysis, allowing you to interleave code, visualizations and explanations
- Keep notebook code cells focused by limiting each cell to a single task for easier flow
- Next steps: add more tests to improve code coverage, continue modularizing components as the project scales, consider ways to further leverage notebook structure
