What are the best practices for using the 'extend' feature in programming?
When using 'extend', ensure you understand the base class thoroughly. Avoid deep inheritance chains.
Can you explain why deep inheritance chains are problematic?
Deep inheritance can lead to complexity, making code harder to maintain and understand. It can also introduce bugs.
What are some alternatives to using 'extend'?
Consider composition over inheritance. Using interfaces or mixins can provide more flexibility and reduce complexity.
How can I determine when to use 'extend' versus composition?
Use 'extend' when you have a clear hierarchical relationship. Opt for composition when behaviors need to be shared across classes.
