Title Case capitalizes the first letter of each word (like in book titles or headlines). For example, 'the quick brown fox' becomes 'The Quick Brown Fox'.

What is camelCase used for?

camelCase is commonly used for variable names in JavaScript and other programming languages. The first word is lowercase, and subsequent words start with capitals: 'getUserName'.
