What is the impact on performance between pass by value and pass by reference?

What is the impact on performance between pass by value and pass by reference?

The main difference lies in how data is handled. Pass by value creates a copy of the data, while pass by reference uses a reference to the original data.

Which one is generally faster?

Pass by reference is usually faster because it avoids the overhead of copying large data structures.

Are there any downsides to using pass by reference?

Yes, pass by reference can lead to unintended side effects since changes to the data affect the original object.

In what scenarios should I prefer pass by value?

You should prefer pass by value when you want to ensure that the original data remains unchanged, especially in multi-threaded environments.
