Hi John!

Frankly, it's pretty hard to suggest anything at this level. I suggest you try to implement this all without any pattern in mind, and then if you discover some pain points, research what pattern can solve them (if you need any at all).

By the way, thank you for supporting the Ukrainian people!

Hi!

Imagine a youtube video player.

The relation between the play button and the player itself is a composition — the play button doesn't make sense outside of the player.

Now, imagine a playlist with a bunch of players. The relation between each player and the playlist itself is an aggregation — a player can both exists independently or as part of a playlist.

Hi!

Yes, the book has been recently translated into Korean as well.

Yes, that's correct, stars mean popularity by the most accurate metric I have — my experience (lol). However, until today, there were some glitches in the Korean version, and the stars didn't appear there correctly, maybe that was a source of confusion.

Thanks a lot for your feedback! I'm glad that you liked my work!

Thank you! I'm glad that you like it!

Hi! Thank you for the idea. I'll consider it when Apple makes the fees more reasonable.

Hi all!

We are actually very close to releasing the Korean 1.0 release. At this stage, I would be glad to get some early feedback from real users. If you have a few hours of spare time to participate in the beta review, please send me an email to support@refactoring.guru and I'll send you the detailed instruction on how to proceed.

Радий, що вам сподобалось, Вадиме!
