As far as I know there are these;
- Camel case = coolFileName
- Snake case = cool_file_name
- Kebab case = cool-file-name
- Pascal case = CoolFileName
- Dot notation = cool.file.name
- Flat case = coolfilename
- Screaming case = COOLFILENAME
Personally I prefer the kebab/dot conventions simply because they allow for easy “navigation” with (ctrl+arrow keys) between each part. What are your preferences when it comes to this? Did I miss any schemes?
General purpose: Kebab case
But really, follow the conventions of what you’re working on. For example, I’d use pascal case when working on a Java/Kotlin project, and snake case when working on a Python project.
