Frequently Asked Questions
What is Title Case?
Title Case capitalizes the first letter of each word. It is commonly used for headings, titles, and headlines. Example: "the quick brown fox" becomes "The Quick Brown Fox".
What is Sentence case?
Sentence case capitalizes only the first letter of the first word in each sentence. It is the standard format for regular writing. Example: "the quick brown fox. jumps over" becomes "The quick brown fox. Jumps over".
What is camelCase?
camelCase is a naming convention used in programming where the first word is lowercase and subsequent words start with uppercase, with no spaces. Example: "user login form" becomes "userLoginForm". Widely used in JavaScript and Java.
What is PascalCase?
PascalCase is like camelCase but the very first letter is also capitalized. It is commonly used for class names in C#, Java, and TypeScript. Example: "user login form" becomes "UserLoginForm".
What is snake_case?
snake_case separates words with underscores and uses all lowercase letters. It is standard in Python, Ruby, and database column naming. Example: "user login form" becomes "user_login_form".
What is kebab-case?
kebab-case uses hyphens to separate words, all in lowercase. It is widely used in URLs, HTML attributes, and CSS class names. Example: "user login form" becomes "user-login-form".
