What naming convention do you use for functions and variables?

The convention can vary by language and ecosystem. For instance, snake_case is common in some C++ projects, while camelCase is widely used in Swift. The important thing is to match the surrounding project rather than changing styles based on mood.

Pick one style and stick with it. Mixing snake_case, camelCase, and PascalCase makes it harder to remember how identifiers are written and makes the code feel inconsistent.

I follow the standard convention for whatever language I’m using. For example, camelCase is common for Java methods, while C# commonly uses PascalCase for methods.

The existing codebase should usually be the deciding factor. If there isn’t an established style, follow the language’s official guidelines or the conventions suggested by your IDE. Consistency matters more than personal preference.
