"The thing that's most impressive about Learn You a Haskell for Great Good! is how well-written it is. This book is just fantastic." —Gregory Collins, Google Switzerland "Managed to walk me through all important Haskell concepts without ever making any of the material sound complicated. A good introduction to functional programming." —Marijn Haverbeke, author of Eloquent JavaScript "This is a fantastic book and I highly recommend it as the first book on Haskell—and possibly even the second." —Michael Fogus, author of The Joy of Clojure "A fantastic, fun, thorough introduction to Haskell, spiced up by Miran's great sense of humor and zany illustrations." —Brent Yorgey, The Math Less Traveled "Miran Lipovača has done a fantastic job of writing a book aimed at beginning Haskell programmers. I like his very straightforward writing style of introducing each topic with the minimum of complexity." —Bryan Bell, Math and More "This is a remarkable book and may be just what this beautiful language was missing." —Michael Kohl, Citizen428 "This book is the best way I know to obtain the Haskell foundation you need for fluency." —Jeremy Bowers, Jerf.org "This is a terrific book. It makes what might otherwise seem impenetrable mathy-code and makes it fun and approachable." —Simon Reynolds
