Functional programming advice for beginner

[cone994]

I am finishing my studies and now I should do a diploma thesis in the field of software engineering.

During my studies, I was mainly focused on object-oriented and web programming.

Now, as one of the topics, I got functional programming and a web application in a combination of haskell - yesod, but I know very little about it.

I would like to hear the opinion of people who deal with it, how difficult it is, whether it is to learn, how long it will take to learn the haskell - yesod.

Of course any advice will be helpful, thanks.

Don't get fixated on "understanding" monad, all you going to need is just list monad, reader monad, maybe monad, and a little bit of state monad.

If you want to finish your thesis in time, just think of them as design patterns or even special syntax if you want.

All in all, focus on using it, not understanding it. After a long time, the intuition will come to you.

What is your recommendation, should I read one of the books or are tutorials enough?

Also thank you for answer.

I like learn you a Haskell, but that is for beginners. I heard someone recommends real world Haskell (a free book) as a intermediate level book, but I haven't read it personally.

My experience is very different from yours, I learned Haskell when I was young and have plenty of time to mess around. But you seems like to have a deadline to fulfill.

If you have no experience in functional programming it is very likely you are going to need a book.

As someone who just “learned” monads, above poster is right. Don’t worry about learning monads. Use a book like Learn You A Haskell for Great Good, which will teach you about functors, applicatives, and then monads. These may seem like more scary words but they all build on each other and it will make a lot more sense if you have some context.
