Haskell is a purely functional programming language with strong emphasis on type safety and lazy evaluation, making it ideal for mathematical and theoretical applications. In contrast, F# is a multi-paradigm language that integrates seamlessly with the .NET ecosystem, making it a great choice for developers working within that framework who benefit from object-oriented features and rich libraries.
