HC19-19. Haskell Chapter 19 Practical Tasks: Applicative |
This lesson covers Applicative Functors, which extend Functors by enabling multi-argument function application within a context. They bridge the gap between simple Functors and more powerful abstractions like Monads. By the end, you'll see why Applicatives are essential and how they provide a structured way to work with functions in contexts.
? Key Topics
Why Applicative Functors? - Understanding how they solve the limitations of plain Functors.
Function application at the Functor level - Using <*> for contextual application.
Being pure - Lifting ordinary values into a context with pure. |
