❓ Frequently Asked Questions

Title Case capitalizes the first letter of each major word: "The Quick Brown Fox Jumps Over the Lazy Dog". Minor words (a, an, the, but, or) are typically lowercase unless at the start.

camelCase is the standard naming convention in JavaScript, Java, and Swift for variables and function names: myVariableName, getUserData, handleClick.

snake_case uses underscores between words: user_first_name, get_api_response. It is the standard convention in Python, Ruby, and database column names.

PascalCase capitalizes the first letter of every word: UserProfile, MyComponent. camelCase keeps the first letter lowercase: userProfile, myComponent.

kebab-case uses hyphens between lowercase words: my-page-title, background-color. It is the standard for HTML attributes, CSS class names, and URL slugs.

UPPERCASE is used for abbreviations (NASA, HTML), constants in programming (MAX_VALUE), and emphasis in writing. Avoid using it for long text — it is harder to read.

Sentence case capitalizes only the first word: "The quick brown fox jumps over the lazy dog." It is the standard format for email subjects and social media posts.
