In computer programming languages, different case styles are used in method, function, variable names or classes.

Camel case

There are 2 type of camel cases: upper camel case and lower camel case.

• For the upper camel case, the first letter of each word is capitalized. For example, DoSomethingAwesome.
• For the lower camel case, only the first letter of the first word is lowercase. The first letter of the other words are capitalized. For example, DoSomethingAwesome.
