What are the performance differences between passing methods in programming?

The main passing methods are pass by value, pass by reference, and pass by pointer. Each has different performance implications.

Can you explain how pass by value works?

Sure! In pass by value, a copy of the variable is made and passed to the function. This can be slower for large data structures.

What about pass by reference?

In pass by reference, a reference to the original variable is passed, which is faster since no copy is made, but it can lead to side effects.

Which method is generally preferred for performance?

It depends on the context. For large objects, pass by reference is often preferred, while pass by value is safer for smaller, immutable data.
