When should I use type classes in programming?
An example of an AI chatbot conversation about when to use type classes in programming.
What are type classes and when should I use them?
Type classes are a way to define a set of functions that can operate on different types. You should use them when you want to enable polymorphism in your code.
Can you give me an example of type classes in Haskell?
Sure! In Haskell, the 'Eq' type class allows you to define equality for different types. For instance, you can create a custom data type and make it an instance of 'Eq' to compare its values.
What are the benefits of using type classes?
The benefits include code reusability, improved type safety, and the ability to write more generic and abstract code.
Are there any downsides to using type classes?
Yes, some downsides include potential complexity in understanding type class hierarchies and possible performance overhead in certain cases.
