## Usage

```js

```

## API

```diff
foo/
└─┬ a/
-  ├── aa/

  │ │ ├── one.txt
  │ │ └── two.txt
-  ├── cc/

```

### 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/']
```
