In C/C++, for an array a, I just learned that (void*)&a == (void*)a. How does that work?

So, I always knew that the array "objects" that are passed around in C/C++ just contained the address of the first object in the array.

How can the pointer to the array "object" and it's contained value be the same?

Could someone point me towards more information maybe about how all that works in assembly, maybe.
