Characters
Explore the Char type in Haskell and how to work with characters using the Data.Char module. Understand how to check character classes like letters and digits, convert characters to Unicode codes with ord and chr functions, and apply character transformations. This lesson helps you handle basic character operations in functional programming using Haskell.
