/**
 * The Promise.allSettled() method returns a promise that resolves
 * after all of the given promises have either resolved or rejected,
 * with an array of objects that each describe the outcome of each promise.
 *
 * For each outcome object, a `status` string is present.
 * If the status is "fulfilled", then a `value` is present.
 * If the status is "rejected", then a `reason` is present.
 * The value (or reason) reflects what value each promise
 * was fulfilled (or rejected) with.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
