Learn You a Haskell for Great Good (2008)

I think the current &#x27;definitive&#x27; resource for learning Haskell is <a href="https://github.com/bitemyapp/learnhaskell" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bitemyapp&#x2F;learnhaskell</a>, which has well-curated, comprehensive links.

Haskell is such a great language. I&#x27;ve been recommending this book for a while now. If you are in doubt whether you should start learning it, read this post by Jeff Bone:<p><a href="http://www.xent.com/pipermail/fork/Week-of-Mon-20070219/044101.html" rel="nofollow">http:&#x2F;&#x2F;www.xent.com&#x2F;pipermail&#x2F;fork&#x2F;Week-of-Mon-20070219&#x2F;0441...</a><p>After I read it, I immediately began learning Haskell. Since then, Haskell made my brain melt multiple times. But it has also enabled me to build an expression parser and analytic differentiator that I use every day (among other things, but that&#x27;s what I&#x27;m most proud of). Such a program would be a lot harder to create, if it weren&#x27;t for Haskell&#x27;s ridiculously powerful type system and pattern matching.<p>Also, after learning the Haskell way of things, I recognized the reasons for many issues I had with code written in another programming language. Don&#x27;t just go out there and do object-oriented programming because everybody else seems to do it, often it is imperative (pun intended) to use the declarative (functional) programming paradigm to keep you out of debugging hell.<p>edit: clarification

We&#x27;d be remiss not to mention the Erlang counterpart...<p><a href="http://learnyousomeerlang.com/" rel="nofollow">http:&#x2F;&#x2F;learnyousomeerlang.com&#x2F;</a>

What is a good online reference to learn about &quot;Monads&quot; for beginners? Someone posted a reference here on HN sometime ago but I lost it.<p>Edit: The book was enjoyable and a delight to read, but I started struggling to keep up from Chapter 8. as it went into Monoids and Monads, I feel like I need to read other tutorials before coming back to it.

I want to note that LYAH may not work for you if you have my kind of learning style. I need to solve concrete, realistic problems to creatively use the knowledge imparted on me. I can&#x27;t just read stuff and understand. Real World Haskell [1], the course by Erik Meijer [2] and the courses referenced here [3] worked much better for me.<p>[1] <a href="http://book.realworldhaskell.org/" rel="nofollow">http:&#x2F;&#x2F;book.realworldhaskell.org&#x2F;</a><p>[2] <a href="https://www.edx.org/course/introduction-functional-programming-delftx-fp101x" rel="nofollow">https:&#x2F;&#x2F;www.edx.org&#x2F;course&#x2F;introduction-functional-programmi...</a><p>[3] <a href="https://github.com/bitemyapp/learnhaskell" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bitemyapp&#x2F;learnhaskell</a>

That sun cracks me up almost every time.

I like Haskell for the same reasons I like VIM:<p>- It needs some brain melting to learn but it ultimately makes you a better coder. Time is not wasted on learning it. - A new exciting mindset !<p>- When you feel you&#x27;re doing something repetitive, it&#x27;s nearly sure there is a way to do it effortless.<p>- Advanced stuff

For newcomers I&#x27;d suggest this introductory course by Erik Meijer: <a href="https://www.edx.org/course/introduction-functional-programming-delftx-fp101x" rel="nofollow">https:&#x2F;&#x2F;www.edx.org&#x2F;course&#x2F;introduction-functional-programmi...</a> . It&#x27;s about FP, not strictly Haskell, but it really helped me starting with it and really stimulated my curiosity (and he really can explain hard concepts in a simple way imo). I started reading the book after I completed the course and helped giving an answer to a lot of questions I had during the course.

I&#x27;m currently working through this book. Overall it seems like a good introduction but I wish it had exercises at the end of each section. I learn best by working through specific problems.

I suggest the Haskell Wikibook as the best overall intro to Haskell actually: <a href="http://en.wikibooks.org/wiki/Haskell" rel="nofollow">http:&#x2F;&#x2F;en.wikibooks.org&#x2F;wiki&#x2F;Haskell</a><p>(and you can make it better if you find anything to complain about! but seriously, it&#x27;s superb)

Supremely useful reference: <a href="http://dev.stephendiehl.com/hask/" rel="nofollow">http:&#x2F;&#x2F;dev.stephendiehl.com&#x2F;hask&#x2F;</a>

Should I learn oCaml instead ? Looks appealing because companies like Facebook are using it create tools like Flow ( <a href="https://github.com/facebook/flow" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;facebook&#x2F;flow</a> ).

This is what I used to learn Haskell a while back. It&#x27;s a pretty darn good intro. I&#x27;m very glad I did it.

I really like this book, but I think it may be teaching some bad habits by ignoring performance concerns.

Haskell can be very handy at solving some puzzles.

This book was excellent for helping me learn Haskell, but the gendered language and fat-shaming jokes made me feel <i>very</i> uncomfortable, eg:<p>&quot;You&#x27;re fat! Lose some weight, fatty!&quot;,&quot;You&#x27;re supposedly normal. Pffft, I bet you&#x27;re ugly!&quot; and &quot;You&#x27;re a whale, congratulations!&quot;, &quot;Sure, we could just type them all out but obviously that&#x27;s not a solution for gentlemen who demand excellence from their programming languages.&quot;

I always have been interested on haskell.... but it doesn&#x27;t look to be enough practical. For example there is almost no information about how to write a smartphone videogame in haskell, even if it possible to trasnpile it to C or to Javascript. It is possible to interoperate with the host language? Does it perform well for high performance activities? Is it possible to isolate some kind of events in a thread?<p>Edit: This lack of practical approach is what makes me hesitate in contrast to clojure (just to mention a language), especially if the only goal is to become again a &quot;better developer&quot; rediscovering functional terms and abstractions also documented in other languages.
