There are definitely two kinds of coders - once that think through everything or at least when it comes to names, method definitions and such they just know what they want. Then there are people like me who is never satisfied with the name or the parameters or the order in which they are passed or the name of the parameters or how the function is structured and want to split it further...etc. So I'm constantly reaching for the refactoring tools of IntelliJ.

OR, as you said, since I have mostly used IDEs all my life, I've learnt to leverage these tools and so I don't always aim to write something to perfection the very first time. Instead I use my IDE as a whiteboard and see where it goes.
