The Haskell blog has published an explanation of the differences between foldl and foldr, the two core folding functions used to reduce lists to a single value. The post clarifies how each function's direction of evaluation affects laziness, stack usage and, in some cases, whether a computation terminates at all. Readers are discussing the practical implications for writing efficient functional code.
