Memento |

This is a companion discussion topic for the original entry at

The contents of starter and final folders for almost all the playground projects have been interchanged, just thought I’d notify :slight_smile:

@jrg.developer Can you please help with this when you get a chance? Thank you - much appreciated! :]

Whoops, this one is indeed flipped :flushed:

We’ll get this fixed and audit the others… thanks for pointing this out!

I don’t get it that why use the memento. Even Comment following code in this playground, it still works!
typealias GameMemento = Data

Could you explain more for that?

Anyway, I think you should change folder between starter and final. I found that code in starter folder.

@jrg.developer Do you have any feedback about this? Thank you - much appreciated! :]

In this case, the Memento type is simply Data. To make this obvious in the playground example, this typealias adds another “name” for Data – that is, GameMemento.

You could indeed simply use Data throughout the playground too. This is merely a hint to indicate to other readers (developers) what your intentions are. :]
