Frequently Asked Questions
What is camelCase?
camelCase starts with a lowercase letter, with each subsequent word capitalized (no separators). Example: 'myVariableName'. It's the standard in JavaScript, Java, and TypeScript for variable and function names.
What's the difference between camelCase and PascalCase?
PascalCase (also called UpperCamelCase) capitalizes the first letter too: 'MyClassName'. It's used for class names in most languages. camelCase keeps the first letter lowercase: 'myFunction'.
When should I use snake_case vs kebab-case?
snake_case (words_separated_by_underscores) is standard in Python, Ruby, and database columns. kebab-case (words-separated-by-dashes) is used for CSS classes, URLs, and file names.
What are Title Case rules?
In Title Case, major words are capitalized while minor words (a, an, the, in, on, at, for, etc.) stay lowercase unless they're the first or last word. Different style guides (AP, Chicago, APA) have slightly different rules.
