I have a function called getItems that returns an array of objects asynchronously. Each object has a isOccupied method that returns a boolean. I wrote a function that takes an index and returns whether index-th item in the array's isOccupied is true or false.
async itemIsOccupied(index) {
return getItems().then(items => {
if (items.length - 1 < index) return false;
return items[index].isOccupied()
});
}
This just works fine, but the fact that I have to use an async function to fetch the array makes it lengthy. Is there a way to simplify this?
I'd clean it up a little like this...
async itemIsOccupied(index) {
const items = await getItems();
return index < items.length && items[index].isOccupied();
}
