World Haskell | Real

: Haskell makes a strict distinction between "pure" code—functions that always return the same output for the same input—and code that performs side effects (like writing to a file). This separation, managed via the IO Monad , makes programs easier to test and reason about.

: Haskell is non-strict, meaning it defers computations until their results are actually needed. In a "real-world" context, this allows for modularity but requires careful profiling and optimization to avoid memory leaks. Notable Real-World Applications Real World Haskell
