What are reference data types in JavaScript?

Can you explain what reference data types are in JavaScript?

Sure! In JavaScript, reference data types include objects, arrays, and functions. They store references to the actual data rather than the data itself.

How do reference types differ from primitive types?

Primitive types, like numbers and strings, hold their values directly, while reference types hold a reference to the value in memory.

Can you give me an example of a reference type?

Absolutely! An example of a reference type is an array. When you create an array, you're creating a reference to a location in memory where the array's elements are stored.

What happens if I assign a reference type to another variable?

If you assign a reference type to another variable, both variables will point to the same object in memory. Changes made through one variable will affect the other.
