async function or async => when exporting default?
arrow-functions, async-await, es6-modules, javascript, node.js
Solution
The first one is generally preferred. It's a declaration, not an expression value, which has subtle advantages. And it can easily be named if you want, which is a good practice. Also, arrow functions have a few disadvantages in certain situations, so unless you absolutely need them to preserve a `this` value (etc.) you'd rather avoid them. Saving 5 characters to type is hardly worth it.
Problem
``` export default async function () { }; ``` or ``` export default async () => { }; ``` Which one is preferred when exporting a default function and why?
