Nowadays u do

foo.js

const wait = ms => new Promise(resolve => setTimeout(resolve, ms))

async function foo() {
    console.log('called')
    await wait(1000)
    return 'hi'
}

export default foo()

index.js

import foo from './foo'

void (async function() {
    console.log(foo)
    console.log(await foo)
    console.log(await foo)
})()

output

> called
> Promise {  }
> hi
> hi

It's usefull to fetch datas at start
