Discussion on: under_scores, camelCase and PascalCase - The three naming conventions every programmer should be aware of

[Truong Hoang Dung]

Never use any of those.

One reason: In some RDBMS, column name is insensitive about those cases.

Use first_name instead of firstName , or FirstName and you'll always be fine.

Yep, even in php, function names are case insensitive. A call to someFunc() or SomeFunc() or even somefunc() all go to the same function.

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!
