ਹੈਸਕਲ (ਅੰਗਰੇਜ਼ੀ: Haskell) ਇੱਕ ਪ੍ਰਮਾਣਿਕ੍ਰਿਤ, ਆਮ-ਮਕਸਦ ਫੰਕਸ਼ਨਲ ਪ੍ਰੋਗਰਾਮਿੰਗ ਭਾਸ਼ਾ ਹੈ। ਇਸ ਦਾ ਨਾਮ ਹੈਸਕਲ ਕਰੀ ਨਾਮ ਦੇ ਦਾਰਸ਼ਨਿਕ ਤੋਂ ਰਖਿਆ ਗਿਆ ਹੈ। ਮਈ 2016 ਤੋਂ ਇੱਕ ਗਰੁੱਪ ਅਗਲੀ ਵਰਜਨ, Haskell 2020,ਉੱਪਰ ਕੰਮ ਕਰ ਰਿਹਾ ਹੈ।[26]

ਕੋਡ ਮਿਸਾਲ[ਸੋਧੋ]

ਹੇਠ ਦਿੱਤਾ ਹੈਲੋ ਵਿਸ਼ਵ ਪ੍ਰੋਗਰਾਮ ਹੈਸਕਲ ਵਿੱਚ ਲਿਖਿਆ ਗਿਆ ਹੈ:[because 1]

module Main where

main :: IO ()
main = putStrLn "Hello, World!"

ਫਿਬੋਨਾਚੀ ਨੰਬਰ ਦੀ ਇਕ ਕੁਸ਼ਲ ਤਾਮੀਲ ਇੱਕ ਅਨੰਤ ਸੂਚੀ ਦੇ ਤੌਰ ਤੇ ਹੇਠ ਦਿਤੀ ਗਈ ਹੈ:

-- Type annotation (optional)
fib :: Int -> Integer

-- With self-referencing data
fib n = fibs !! n
        where fibs = 0 : scanl (+) 1 fibs
        -- 0,1,1,2,3,5,...

-- Same, coded directly
fib n = fibs !! n
        where fibs = 0 : 1 : next fibs
              next (a : t@(b:_)) = (a+b) : next t

-- Similar idea, using zipWith
fib n = fibs !! n
        where fibs = 0 : 1 : zipWith (+) fibs (tail fibs)

-- Using a generator function
fib n = fibs (0,1) !! n
        where fibs (a,b) = a : fibs (b,a+b)

The Swift language is the product of tireless effort from a team of language experts, documentation gurus, compiler optimization ninjas, and an incredibly important internal dogfooding group who provided feedback to help refine and battle-test ideas. Of course, it also greatly benefited from the experiences hard-won by many other languages in the field, drawing ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list.
