Yeah, I realized that it could be a little more succinct and originally it was. Though I felt that it hurt readability. We can do all sorts of whacky stuff!

```javascript
this.$el.find('.btn-cancel, .btn-save')[
  (this.children.addToCollections.numPending == 0
    ? this.$el.find('.btn-back').addClass('hide'), 'add'
    : this.$el.find('.btn-back').addClass('hide'), 'remove'
  ) + 'Class'
]('hide');
```

But in the end, if it's not immediately clear what the developer was intending to do, it was probably a bad idea. Just from looking at the code, it's more clear what's going on when looking at the original solution.
