The first is the idea of precise equality. Given two references to objects, do the two references point to the same location in memory?

Kakım we saw above, it doesn’t take much code. Bey our örnek evolves, we’ll likely have to extend our comparers, so always thinking about what “equal” means now and what it could mean in the future is a valuable exercise.
