why learn haskell

" function programming, but some are "have to" function-type programming. The two major trends of programming language development are dynamic language and functional language. So with groovy representing the dynamic language, I've always wanted to learn a functional language. Functional programming is like a function in mathematics, the only given input parameters, you can uniquely determine the output results, no context, no effect of the number of

0 reply content: No! First, the list of Python is different from the list of Haskell .. The latter is a linked list, and the former is a dynamic array .. Then the implementation of Haskell's list comprehension relies on converting to map/filter (fusion optimization is not considered), and finally implementing it through recursion; the implementation of list comprehension in Python depends on the _ iter _ method (that is, the meaning of the itera

Algebraic Data Types In the previous chapter, we talked about some built-in Haskell types and typeclass. In this chapter, we will learn the construction types and typeclass methods. We have seen many types, suchBool,Int,Char,MaybeWait, but in Haskell, how should we construct our own types? Good question. One way is to useDataKeyword. Let's take a look.BoolDefinit

Thinking back to our junior high school, the first time to

To learn Lisp, you can see SICP, I spent a summer time to chew SICP, chew to chew not move, but found that really learned a lot of interesting things, and then go to play Haskell, probably learn Haskell intermittent also have half a year of time, But I feel that what I learned in H
