maybe a naming like: `Promise.allObject`
```js
Promise.allObject = obj => {
if (obj && !obj[Symbol.iterator]) {
return Promise.all(
Object.entries(obj).map(async ([k, v]) => [k, await v])
)
.then(Object.fromEntries);
}
return Promise.all(obj);
}
var delay = t => new Promise(r => setTimeout(r, t));
console.time(1); console.log(await Promise.allObject({foo:
delay(110).then(()=>1), bar: delay(120).then(()=>2)})); console.timeEnd(1)
```
