Frequently Asked Questions

Where do camelCase, PascalCase, snake_case, and kebab-case belong?
Mainstream conventions: camelCase for JS/Java variables and methods; PascalCase for classes, components, and types; snake_case for Python and database columns; kebab-case for CSS classes, URLs, and filenames. HTTP headers are kebab but case-insensitive. Ecosystem conventions beat personal preference.
Why do automatic converters mishandle acronyms?
"parseXMLFile" should become parse_xml_file, but naive algorithms split runs of capitals wrong (parse_x_m_l_file). The tool applies common acronym rules (consecutive capitals treated as one word), but names like APIName or HTTPServer deserve a manual glance.
Can case conversion corrupt data?
Pure ASCII is safe, but watch for non-reversible cases (German ß uppercases to SS) and case-sensitivity differences in filesystems (macOS default insensitive, Linux sensitive) — kebab-casing filenames is good hygiene against case collisions.
