Frequently asked questions
What's the difference between camelCase and PascalCase?
Both join words without spaces and capitalize each word. camelCase starts lowercase (myVariableName); PascalCase starts uppercase (MyVariableName) — common for classes and components.
Does the converter handle acronyms?
Yes — reasonable rules keep acronyms like 'HTML' or 'API' intact in Title and sentence cases instead of capitalizing every letter oddly.
Is snake_case the same as kebab-case?
No. snake_case joins words with underscores (my_variable), kebab-case uses hyphens (my-variable). Both are all-lowercase.
Can I use it for file names?
Yes — kebab-case and snake_case outputs are ideal for file names, while CONSTANT_CASE suits environment variables.
