quite clean and minimal async http call
const r2 = require('r2')
// asynchronous arrow functions seem to need an explicit return to work properly
const loadUser = async id => { return await r2(`https://jsonplaceholder.typicode.com/users/${id}`).json }
(async function() {
console.log(await loadUser(2))
})()
