Haskell is a purely functional programming language with strong static typing and lazy evaluation.

Key Features:

• Pure functional (no side effects)
• Lazy evaluation
• Strong static typing
• Type inference
• Pattern matching

Hello World:

main = putStrLn "Hello, Haskell!"

Basic Values:

number = 42
name = "Haskell"
isTrue = True
listOfNumbers = [1, 2, 3, 4, 5]
