Frequently Asked Questions
Title Case capitalises the first letter of each major word. Small words like "a", "an", "the", "and", "or", "but", "in", "on", "at", "to", "for", "of" are kept lowercase unless they are the first or last word.
Sentence case capitalises only the first letter of each sentence and proper nouns. Everything else is lowercase. It mimics how you would write an ordinary sentence.
camelCase is widely used in programming — for variable names in JavaScript, Java, and Swift. The first word is all lowercase; every subsequent word starts with a capital letter: myVariableName.
snake_case uses underscores instead of spaces and all letters are lowercase. It is the convention for variable names in Python, Ruby, and SQL column names.
kebab-case uses hyphens instead of spaces and is all lowercase. It is the convention for CSS class names, HTML attributes, URL slugs, and file names in web projects.
