Sentence case & Title Case
- Sentence case: Capitalizes only the first letter of each sentence, matching standard grammar layouts.
- Title Case: Capitalizes the first letter of major words, ideal for headers, essays, and title structures.
Programming Cases
- camelCase: Lowercase first word, capitalize subsequent words, with spaces stripped. Often used in Javascript variables.
- PascalCase: Capitalize every word, with spaces stripped. Often used for class names in OOP.
- snake_case: All words lowercased, separated by underscores (`_`). Often used in database fields and Python scripts.
- slug-case: All words lowercased, separated by dashes (`-`). Often used in web URL structures.
Playful Cases
