Learn You a Haskell for Great Good! is a fun, illustrated guide to learning Haskell, a functional programming language that's growing in popularity. Learn You a Haskell for Great Good! introduces programmers familiar with imperative languages (such as C++, Java, or Python) to the unique aspects of functional programming. Packed with jokes, pop culture references, and the author's own hilarious artwork, Learn You a Haskell for Great Good! eases the learning curve of this complex language, and is a perfect starting point for any programmer looking to expand his or her horizons. The well-known web tutorial on which this book is based is widely regarded as the best way for beginners to learn Haskell, and receives over 30,000 unique visitors monthly.

- "我们看到如何在函子值上映射“多参数”函数得到函数值的函子值。我们能对它做什么吗？对于一个参数，我们可以映射一个函数，它接受某个函数为参数，给这个函数应用一个参数。因为函子值里的任何东西都会被作为参数传递给我们的函数。"
- "_ means that we don't care what we'll draw from the list anyway so instead of writing a variable name that we'll never use, we just write _."
- "Use tuples when you know in advance how many components some piece of data should have. Tuples are much more rigid because each different size of tuple is its own type, so you can't write a general function to append an element to a tuple — you'd have to write a function for appending to a pair, one"
- "In our gcd' function, the logging is fast because the list appending ends up looking like this: a ++ (b ++ (c ++ (d ++ (e ++ f)))) Lists are a data structure that's constructed from left to right, and this is efficient because we first fully construct the left part of a list and only then add a long"
- "Function application has the highest precedence of all the operations in Haskell. In other words, these two statements are equivalent."
- "This example introduces Haskell’s if statement. You’re probably already familiar with if statements from other languages, but what makes Haskell’s unique is that the else part is mandatory. On the other hand, a Haskell program is a collection of functions. Func- tions are used to transform data valu"
- "Accessing List Elements If you want to get an element of a list by index, use the !! operator. As with most programming languages, the indices start at 0:"
- "multThree :: Int -> Int -> Int -> Int multThree x y z = x * y * z"
