Camel Case (camelCase)

Camel case combines words by capitalizing all words following the first word and removing the space, as follows:

Camel Case: userLoginCount

This is a very popular way to combine words to form a single concept. It is often used as a convention in variable declaration in many languages.

Pascal case combines words by capitalizing all words (even the first word) and removing the space, as follows:

Raw: user login count

Pascal Case: UserLoginCount

Snake case combines words by replacing each space with an underscore (_).

Raw: user login count

Snake Case: user_login_count

It is used conventionally in declaring database field names.

In the "all caps" version, all letters are capitalized, as follows:

Raw: user login count

Snake Case (All Caps): USER_LOGIN_COUNT
