CamelCase is a naming convention where variables are written with no separating punctuation, and each word within the compound word starts with a capital letter (except the first one), e.g., 'userName'.

Snake_case is a naming convention where words are separated by underscores '_', and usually all letters are lowercase, e.g., 'user_name'.
