#### BooleanArray.prototype.toReversed()

Returns a new typed array containing the elements in reversed order.

```javascript
var arr = new BooleanArray( 3 );

arr.set( true, 0 );
arr.set( false, 1 );
arr.set( false, 2 );

var out = arr.toReversed();
// returns <BooleanArray>

var v = out.get( 0 );
// returns false

v = out.get( 1 );
// returns false

v = out.get( 2 );
// returns true
```
