CamelCase

CamelCase is the term used to refer to the convention of joining several words together to form a single name. Medial capitals (capital letters in the middle of a word) are used so that each word can be clearly distinguished and the name easily read. There are two types of CamelCase: in UpperCamelCase the first letter of the name is capitalized; in lowerCamelCase it is lowercased. It has been used for centuries in the spelling of certain names.
