WebThus, the function sort has a generic type-parameter t (we’ll talk more about such parametric polymorphism in haskell later) which is constrained to be in the Ord type class (anything that is orderable - we’ll talk more about type classes too). It’s input parameter is a list of t, as is its return type.This is also precisely the syntax that one would use to … WebUnlike Java or Pascal, Haskell has type inference. If we write a number, we don't have to tell Haskell it's a number. It can infer that on its own, so we don't have to explicitly write out the types of our functions and expressions to get things done. We covered some of the basics of Haskell with only a very superficial glance at types.
