What are the differences between type constraints and type classes?
An example of an AI chatbot conversation about type constraints vs type classes in programming.
What are the differences between type constraints and type classes?
Type constraints are conditions that types must satisfy in a function, while type classes define a set of types that share common behavior.
Can you give an example of type constraints in Haskell?
Sure! In Haskell, you might see a function like show :: Show a => a -> String, where Show a is a type constraint.
And how do type classes work in practice?
Type classes allow you to define functions that can operate on different types, as long as those types implement the class's methods.
What are some common type classes in Haskell?
Common type classes include Eq for equality, Ord for ordering, and Num for numeric types.
