Introduction

OK. So, it seems as of 2022 or so – the MDN and other documentation is favoring arrow functions for their default examples. We think this is dumb. But what do you think? We’d better talk about it!

Also, it’s not just a syntax choice. The two types of functions do slightly different things in some circumstances.

Since there are so many options… we think we should just PICK ONE and stick with it.

So, our recommendation is to always use parentheses. Then it’s always the same.
