Variations and synonyms

There are two common varieties of CamelCase, distinguished by their handling of the initial letter of what would otherwise be the first of separate words. Where the first letter is capitalized is commonly called UpperCamelCase, PascalCase, or BiCapitalized. Where the first letter is left in lowercase is commonly called lowerCamelCase. This variant has also been occasionally called dromedaryCase or camelCase. For clarity, this article will use the terms UpperCamelCase and lowerCamelCase, respectively.
