Frequently Asked Questions

When should I use Title Case vs Sentence case?
Title Case: book titles, article headlines, formal proper nouns, navigation menu items, CTA button text. Sentence case: body paragraphs, email bodies, informal headings, most UI elements in modern design. Modern content style guides (Google, Microsoft) prefer sentence case for most UI and documentation. Blog post titles typically use title case for SEO (it looks more authoritative in search results).
What is the difference between camelCase and PascalCase?
camelCase: first word lowercase, subsequent words capitalised — myVariableName. Used for variables, function names in JavaScript, Java, C#. PascalCase (UpperCamelCase): every word capitalised — MyVariableName. Used for class names, constructor functions, React component names. Both are compound word formats without spaces.
When is snake_case used in programming?
snake_case uses underscores between words, all lowercase — my_variable_name. Used in: Python (PEP 8 standard for variables and functions), Ruby, Rust, SQL column names, Django model field names, file names. Contrast with kebab-case (my-variable-name) used in CSS classes, HTML attributes and URL slugs.
