What should I avoid when using filter functions?

Avoid using filter functions with side effects, as they can lead to unexpected behavior. Also, try to keep your filter conditions simple.

How can I improve the performance of filter functions?

To improve performance, consider using list comprehensions or generator expressions, as they can be more efficient than traditional filter functions.
