Structure: decades of programming in too many languages to enumerate. I lean functional, but only when the language doesn't fight it. No matter what I'm doing, my code is immutable in practice, if not paradigm.

Syntax: No one thing in particular. I code differently depending on the language.

When I start learning a language, I'll find the standard style checker and create a project where I write an example of every single rule.

The end result is generally a quick intro to the language and a bonus understanding of the hot sports opinion in said language. I call this an ocean boiler.

I lean heavily into autoformatting because I've worked on too many projects to care, and I have a general expectation that something which is important enough to make a code standard is important enough to be enforced in tooling. I'd rather spend my time solving problems that thinking about stylistics.
