PascalCase or camelCase (note the capitalization of the first letter, that’s the difference between the two) basically always.

I really like kebab-case, because I’m a lisp aficionado

Kebab case hands down, it’s as readable as snake case, but easier to type. Unfortunately, it’s rarely seen outside Lisps.

snake_case for variable names because they seem to be holding something in their underscores. camelCase for functions because verbNoun looks good. PascalCase for classes because it looks like it’s a level above that needs to be instantiated before getting used.
