Haskell Functors: Elegantly Handling Values in Context

In Haskell, Functors provide a powerful abstraction for working with values wrapped in contexts like Maybe or lists. The `fmap` function elegantly applies functions to these values, avoiding type errors that would arise from direct function application. The article details the Functor definition, the role of `fmap`, and the identity and composition laws Functors must obey, illustrating with examples using Maybe and lists. It concludes by highlighting the benefits of Functors in creating cleaner, more readable code.
