Frequently asked questions
- What is the difference between camelCase and snake_case?
- camelCase joins words with no spaces and capitalizes each word after the first (myVariableName), while snake_case lowercases everything and separates words with underscores (my_variable_name). Both are common in programming.
- What is kebab-case used for?
- kebab-case lowercases words and joins them with hyphens (my-page-slug). It is widely used for URLs, CSS class names and file names.
- Does Title Case capitalize every word?
- Title Case capitalizes the principal words; many styles leave small words like 'and' or 'of' lowercase. Sentence case, by contrast, only capitalizes the first word and proper nouns.
