The naming styles
b(single lowercase letter)
B(single uppercase letter)
CapitalizedWords(or CapWords, or CamelCase – so named because of the bumpy look of its letters ). This is also sometimes known as StudlyCaps.Note: When using acronyms in CapWords, capitalize all the letters of the acronym. Thus HTTPServerError is better than HttpServerError.
mixedCase(differs from CapitalizedWords by initial lowercase character!)
Class names should normally use the CapWords convention.
Function names should be lowercase, with words separated by underscores as necessary to improve readability. (
Variable names follow the same convention as function names.
