The Haskell Programming Language

Why Choose Haskell?

Haskell is a statically typed, pure-functional programming language known for its strong type system and concise syntax. It is widely used for developing complex software systems due to its ability to handle complex data structures efficiently.

Language Features

• Pure Functions: All functions are pure, meaning their output depends solely on their input and not on the state of the program.
• Type Inference: The compiler can infer the types of variables and expressions without requiring explicit declarations.
• Immutability: Variables cannot be changed once assigned; instead, new values are created through function application.
• Monads and IO: Haskell uses monads to manage side-effects such as I/O operations in a clean and readable way.
• Strong Typing: The language has a strict type system that helps prevent errors at compile time.

Sample Code

import System.IO

main :: IO ()
main = do
    putStrLn "Hello from Haskell!"
    handle <- openFile "hello.txt" WriteMode
    hPrintLine handle $ "Hello from Haskell!" ++ "\n"
    closeHandle handle
