Title Case capitalizes the first letter of each word while making all other letters lowercase. Example: "the quick brown fox" → "The Quick Brown Fox".
camelCase removes spaces and capitalizes the first letter of each word except the first. It's commonly used in programming for variable names. Example: "user first name" → "userFirstName".
snake_case replaces spaces with underscores and makes everything lowercase. It's common in Python and database column names. Example: "User First Name" → "user_first_name".
