While most developers might have their own preferred styles, the recommended or preferred style between languages can vary. As an example, in C#, when we name a method or function, it is preferred that we use PascalCase, which is similar to CamelCase except the first letter is capitalized. In most other languages, such as C, Objective-C, and Java, it is also recommended that we use CamelCase, where the first letter is lowercase.
