hqman / Y Combinator 简介
Created February 3, 2016 08:41 — forked from redraiment/Y Combinator 简介
Y Combinator (Fixed-point Combinator) 不动点组合子
Y组合子是Lambda演算的一部分,也是函数式编程的理论基础。
它是一种方法/技巧,在没有赋值语句的前提下定义递归的匿名函数。
即仅仅通过Lambda表达式这个最基本的“原子”实现循环/迭代。
颇有道生一、一生二、二生三、三生万物的感觉。
虽然Y组合子在理论上很优美,但在实际开发中并不会真的用到。
想要了解Y组合子是什么,请参见维基百科:http://en.wikipedia.org/wiki/Fixed-point_combinator#Y_combinator
