1Web/Frontend Files
kebab-case: my-component.tsx, user-profile.css. This matches URL conventions and is clearly readable.
2Python Files
snake_case: my_module.py, data_processor.py — follows PEP 8 and Python community convention.
3Cross-Platform Note
Windows file system is case-insensitive. Linux is case-sensitive. myFile.txt and myfile.txt are the same on Windows, different on Linux. Always use lowercase to avoid cross-OS bugs.
