Understanding which capitalization style to use helps maintain consistency across content and software engineering:
UPPERCASE
Converts all letters to capital form. Commonly used for prominent warning notices, legal disclaimers, acronyms, and SQL keywords.
lowercase
Turns all letters into small letters. Ideal for normalizing raw database inputs, email addresses, usernames, and URL slugs.
Title Case
Capitalizes the first letter of each significant word. Standard format for blog post headlines, book titles, and email subject lines.
camelCase
Removes spaces and capitalizes the first letter of each subsequent word. The primary naming convention for JavaScript and TypeScript variables.
