Frequently asked questions
What is camelCase vs PascalCase?
camelCase starts with a lowercase letter and capitalizes each following word: myLongVariableName. PascalCase (also called UpperCamelCase) capitalizes every word including the first: MyLongClassName. JavaScript tends to use camelCase for variables and PascalCase for classes and components.
When do I use snake_case vs kebab-case?
snake_case joins words with underscores: user_created_at — the convention in Python and Ruby and for most database column names. kebab-case joins words with hyphens: user-created-at — the convention for CSS classes, URLs, file names and package names in the JavaScript ecosystem.
How does Title Case decide which words to capitalize?
This tool capitalizes every word, which is the safe default for headings. Classic editorial title case (lowercasing short words like 'of' and 'the' unless first or last) varies by style guide, so full capitalization avoids ambiguity.
