Functional Design and Architecture: Examples in Haskell

I love this book, it fills in all the gaps I had in design knowledge coming from a web development background. Finally taking the jump from writing mostly-imperative TypeScript to using a declarative approach with Haskell! The physical book itself is nice, no complaints. The editing is good, the subject matter is good, and the examples are very helpful. 10/10 would recommend!

This is a great bridge book to get into functional programming for people who have been programming in imperative languages. Prior to reading this book I had tried to get into haskell multiple times, but the subject matter always seemed too alien and academic. Because the book contains multiple examples showing first how a problem might be solved in imperative languages and then shows functional approaches to the same problem, I found it very helpful to get the functional point of view. Authors experience working in industry also shows because the examples picked are well representative of problems you run into the trenches of working as a programmer in an industrial setting.

I really want to love this book, because it brings together and integrates many aspects of functional programming at a high level. But man, I find it hard to read. It's very rambling and doesn't get to the point. The prose needs an aggressive editor to make a pass over it. I waited years for this to come out, and now I guess I can't wait for the next edition.

This is a book obviously generated with heavy use of some LLM by an author that obviously has no real world experience. I am also questioning if he has basic knowledge of the subject domain. It is full of platidudes and cliches and because it is easier to copy stuff from object oriented literature directly or via an LLM, he gives examples with Java class diagramms. One is eager to see functional programming related stuff and continues the painful reading, only to be faced with monads etc. My initial reaction, was let's see if I can finally understand monads in the context of a real world example. Again content copied by LLMs. It is literally the worst technical book I have ever bought. I really regret it.
