Great writing again Maxi. 👏
I have to admit I am obsessed with primitives. 😊
But I can answer why.
I am not an OOP purist.
Creating objects for the tiniest variables has its price.
You need to put a lot of extra effort to implement them.
And there is also one more advantage:
During the last decades developers were obsessed with primitives.
But it has also a benefit.
We can easily read and write such code.
Just my 2 cents. 😊
