Fat Object issue mentioned in Chronicles

David talked about object with numProperty > 128 will cause performance issue.
I wonder where I can get more info about it?
Through Inheritance, a class’ member can easily surpass 128.

There is an old blog post about that issue: My fat objects are slower than my thin ones | Eternalcoding

The value is not set in stone, Chrome/Edge specifc as well but trying to not go over is a really good thing :slight_smile:
