### async-await (promise)
If no callback is passed, a promise is returned. Returns the array of deleted directories.
```js
(async () => {
let deleted = await deleteEmpty('foo');
console.log(deleted); //=> ['foo/aa/', 'foo/a/cc/', 'foo/b/', 'foo/c/']
})();
// or
deleteEmpty('foo/')
.then(deleted => console.log(deleted)) //=> ['foo/aa/', 'foo/a/cc/', 'foo/b/', 'foo/c/']
.catch(console.error);
```
### async callback
Returns the array of deleted directories in the callback.
```js
deleteEmpty('foo/', (err, deleted) => {
console.log(deleted); //=> ['foo/aa/', 'foo/a/cc/', 'foo/b/', 'foo/c/']
});
```
### sync
Returns the array of deleted directories.
```js
console.log(deleteEmpty.sync('foo/')); //=> ['foo/aa/', 'foo/a/cc/', 'foo/b/', 'foo/c/']
```
## CLI
