 We also can write a single call per line. For long chains it's more readable:

 Modify the code of `up`, `down` and `showStep` to make the calls chainable, like this:
 
 ```js
-ladder.up().up().down().showStep(); // 1
+ladder.up().up().down().showStep().down().showStep(); // shows 1 then 0
 ```
 
 Such approach is widely used across JavaScript libraries.
