Frequently Asked Questions
What is the difference between all the text case types?
UPPERCASE: ALL CAPS. lowercase: all small. Title Case: First Letter Of Each Word Capitalized. Sentence case: First letter of sentence capitalized. camelCase: wordsJoinedNoCapsFirst. PascalCase: WordsJoinedAllCapped. snake_case: words_with_underscores. kebab-case: words-with-hyphens. Each has specific uses in programming, writing, and web development.
What is snake_case used for?
snake_case is standard in: Python (variables, functions, modules), Ruby (methods, variables), database columns/tables, environment variables, file names (especially in Unix/Linux), and PostgreSQL identifiers. It's readable while avoiding spaces, and works in case-insensitive systems.
What is kebab-case and where is it used?
kebab-case (words-with-hyphens) is used for: URL slugs (/my-blog-post), CSS class names (.my-component), HTML attributes (data-user-id), file names in web projects, npm package names, and Lisp function names. It's URL-friendly and readable in addresses.
How does Title Case differ from Sentence case?
Title Case capitalizes the first letter of every major word: 'The Quick Brown Fox Jumps Over the Lazy Dog.' Sentence case only capitalizes the first letter of the sentence: 'The quick brown fox jumps over the lazy dog.' Some title case styles leave small words (a, an, the, of) lowercase unless first word.
