Frequently asked questions
- What is Title Case?
- Title Case capitalises the first letter of every word. It is commonly used for headings, book titles, and article titles — for example 'The Quick Brown Fox'.
- What is Sentence case?
- Sentence case capitalises only the first letter of the first word in each sentence, matching normal written English — for example 'The quick brown fox jumps over the lazy dog.'
- What is camelCase?
- camelCase joins all words together, lowercasing the first word and capitalising the first letter of each subsequent word — for example 'theQuickBrownFox'. It is widely used for variable names in JavaScript and other languages.
- What is PascalCase?
- PascalCase is like camelCase but capitalises the first letter too — for example 'TheQuickBrownFox'. It is commonly used for class names and component names in many programming languages.
- What is snake_case?
- snake_case replaces spaces and special separators with underscores and lowercases everything — for example 'the_quick_brown_fox'. It is the standard for Python variable names and database column names.
- What is kebab-case?
- kebab-case replaces spaces and separators with hyphens and lowercases everything — for example 'the-quick-brown-fox'. It is used in CSS class names, URL slugs, and file names.
