Refactor duplicate code
Functions getFileIcon() and getLanguage() share similar logic. Consider extracting to a utility.
Optimize Performance
renderFileTree() is called frequently. Memoize results for unchanged data to improve rendering speed.
Use Modern ES6+ Features
Replace var with const/let. Use arrow functions for better code readability.
Add Error Handling
The openFile() function lacks try-catch blocks for error scenarios.
Improve Accessibility
Add aria-labels to interactive elements for screen reader support.
Good: Type Safety
Consider migrating to TypeScript for better type checking and IDE support.
Bundle Optimization
Split code into smaller chunks and implement lazy loading for better performance.
Testing Coverage
Add unit tests for core functionality. Current coverage: 65%.
