Yeah, it's relevant to remember that arrow functions were defined in ES2015 (eight years ago) and like I said most browsers people are using are caught up through at least ES2021. The nice thing about the ES2015 year-based nomenclature (as opposed to the people still calling it "ES6") is that you can do a quick reasonable first approximation of caniuse statistics off hand with "is that standard at least two years old?" Arrow functions are old.
