HKP-Notebook

This repository contains my Haskell learning notes and small practice files.

Documentation overview

• MonadDemo.hs
  Main Note – A step-by-step Monad walkthrough using Maybe:

  • Monad idea: wrap a value together with a context (here: possible failure).
  • Nothing means computation failed, Just x means success with value x.
  • Shows the same evaluator in four styles: nested case, explicit bind, >>=, and do notation.
  • Includes safe division examples so you can see how failure is propagated automatically.

• haskell_summary.md
  The summary of core Haskell topics: list functions, operators, folds, map/mapM, IO basics, and type classes.

• IO_Summary.md
  Focused explanation of IO () vs IO Char using the example functions ff and fff, with behavior examples and intuition about effects vs returned values.
