What are the differences between object pooling and garbage collection?

Object pooling is a design pattern that reuses objects from a pool instead of creating new ones, while garbage collection automatically frees up memory by reclaiming objects that are no longer in use.

When should I use object pooling instead of relying on garbage collection?

You should consider using object pooling when you have a high frequency of object creation and destruction, as it can improve performance by reducing the overhead of memory allocation.

Are there any downsides to using object pooling?

Yes, object pooling can introduce complexity in managing the pool and may lead to memory leaks if not handled properly. It also requires careful tuning of the pool size.

Can you give me an example of a scenario where object pooling is beneficial?

Sure! In a game, if you frequently create and destroy bullets for a shooting mechanic, using an object pool for bullets can significantly reduce lag and improve performance.
