Fix: critical bugs and performance improvements

[modojodo]

Fixes

1. Added TypeScript types - Created Advocate type interface and properly typed all state variables
2. Fixed invalid HTML table structure - Added missing <tr> wrapper around <th> elements in <thead>
3. Added React keys - Added unique key props to both the main table rows and specialty divs to prevent React warnings
4. Fixed search functionality:
   • Made search case-insensitive by converting both search term and data to lowercase
   • Fixed the specialties.includes() bug by using .some() to properly search array elements
   • Fixed the yearsOfExperience.includes() type error by converting number to string
5. Removed DOM manipulation - Replaced document.getElementById().innerHTML with React state (searchTerm)
6. Improved reset functionality - Reset button now properly clears the search term display

Improvements Made

• Type Safety: Added proper TypeScript types for all variables and functions
• React Best Practices: Used React state instead of direct DOM manipulation
• HTML Validity: Fixed invalid table structure that would cause browser parsing issues
• Performance: Eliminated hydration mismatches by using React state consistently
• User Experience: Search now works case-insensitively and properly handles all data types

Status

The development server is running successfully at http://localhost:3000 and the application should now work without the critical bugs that were causing:

• Runtime errors when searching numbers
• Console warnings about missing React keys
• Invalid HTML structure
• Hydration mismatches
• Case-sensitive search issues
