StudlyCaps, also known as PascalCase, implies that the first capital of each subword is capitalized. camelCase implies, like a camel, that the humps are in the middle, therefore the first letter is not capitalized.

Other well known capitalization styles are snake_case, where all words are concatenated in lowercase with underscores, and kebab-case, which is identical but uses a hyphen.
