GHCi

GHCi is an interactive environment for programming with Haskell, a functional programming language. Think of it as a command-line tool where you can write, test, and evaluate Haskell code line by line without creating a complete program first. It helps developers experiment with functions, see results immediately, and debug code efficiently. GHCi simplifies learning and development by providing quick feedback, making it a valuable resource for both beginners and experienced programmers working with Haskell.
