If an author is Amazon exclusive I don’t feel bad getting the book from other sources, and just put it on my Kobo.
If I want to support them, I will buy the book either as a physical book or on Amazon, and read the otherly-acquired book on my Kobo anyway.

Type is more important? So if the first argument of a function is
minAge, which is anint, the important part is that it is anint? Just feed it anyint?No, the important part is the meaning, what the variable actually is, if you use a compiled language the compiler will handle types for you anyway. You’ll get a error if you feed it a string, or an water heater object, no surprises.
Leave the machine work to the machine (compiler in this case), and concentrate on the real work, which is the meaning here.
