Is there a "Why Haskell?" post somewhere out there? I am just curious about what Haskell brings to the table, what it is good at, and does it have a niche. Is Haskell trying to break its bonds in the niche to get to the wider world in general? All sorts of questions like that.
- gaius 16y agoThe big things that Haskell does that no-one[1] else does are a) strict separation of the parts of the program that do I/O or otherwise change some sort of global state and b) lazy evaluation, which means evaluate a function only when it is needed to do (a). The compiler enforces (a). (a) is a big deal because it makes it very easy to reason about what your program does, which is handy because (b) is the opposite :-) but makes certain kinds of computations very elegant to express.
