I see some devs prefer firstName over first_name, which i see is a way to confusion if you use , for example PostgreSQL as column name.
I don't understand why they prefer that option. Maybe because it's "prettier" ?
I'm from Java/Dart background, I also had a similar question for python.
I was thinking why we should type 1 more "_", of course this will take very short time for 1 variable or 1 method, but we will have many of them in a program.
I don't mean underscore is bad, it depends on what you prefer!
