What are object references in Ruby?

What are object references in Ruby?

In Ruby, an object reference is a pointer to an object in memory. It allows you to interact with the object without copying it.

How do object references differ from object copies?

Object references point to the same object, while object copies create a new instance. Changes to a reference affect the original.

Can you give an example of how object references work?

Sure! If you have an array a = [1, 2, 3] and assign b = a, both a and b refer to the same array. Modifying b will change a too.

What happens if I modify an object through a reference?

Modifying an object through a reference will change the original object since both reference the same memory location.
