What are the common reference types in programming?

Common reference types in programming include objects, arrays, and functions. They allow for complex data structures.

Can you explain how objects work as reference types?

Sure! Objects are collections of key-value pairs, where keys are strings and values can be any data type, including other objects.

What about arrays? How are they different from objects?

Arrays are ordered collections of elements, typically of the same type, and are accessed via numeric indices, unlike objects.

Are there any performance implications when using reference types?

Yes, reference types can lead to performance overhead due to memory allocation and garbage collection, especially with large data sets.
