### 3/5 — Good but...

*2020-04-05*

Run this code snippet in the editor and see what happens

a = ("sololearm"..."zzzzzzzzz").to_enum
p a.next.next

### 1/5 — Too confusing

*2019-09-07*

There are several clone apps on the store by the same author and another (rubi ide fresh edition by Na Chen) with same functionality but different price model or slightly different look - why is apple allowing this nonsense. The app is cluttered with crazy stuff like coins etc and is not intuitive. The author should look to play.js app to see how to present a professional looking and respectful developer environment.
