Haskell is a purely functional programming language with strong type safety and lazy evaluation, making it suitable for academic and complex algorithmic tasks. In contrast, Objective-C is an object-oriented language primarily used for iOS and macOS development, offering flexibility and a rich set of libraries, but it is tightly coupled with Apple's ecosystems.
