Example of using Array Destructuring for Promise.all.

promiseall.js

Promise.all([
    someThingThatReturnsAPromise(),
    otherThingThatReturnsAPromise(),
    lastThingThatReturnsAPromise()
])
.then( results =>
{
    // this...
    const [first, second, third] = results;
    // ... instead of
    // const first    = results[0].result;
    // const second   = results[1].result;
    // const third    = results[2].result;
});

@aaronwbrown First, make Promises that don't fail: https://medium.com/@jesterxl/promises-that-dont-fail-bd1fd6139b97

Then you can use async/await without worry: http://jessewarden.com/2017/11/easier-error-handling-using-asyncawait.html
