什么是Y组合器？ [英] What is a Y-combinator?

问题描述

Y-combinator是来自功能的计算机科学概念，事物的一面。大多数程序员对combinators了解得不多，如果他们甚至听说过它们的话。

• 什么是Y组合器？


• 
  
• 
  
• 它们适用于过程语言
如果您准备好进行长时间阅读， Mike Vanier有一个很好的解释。长话短说，它允许您以本地不一定支持它的语言实现递归。



A Y-combinator is a computer science concept from the “functional” side of things. Most programmers don't know much at all about combinators, if they've even heard about them.

• What is a Y-combinator?
• How do combinators work?
• What are they good for?
• Are they useful in procedural languages?

解决方案

If you're ready for a long read, Mike Vanier has a great explanation. Long story short, it allows you to implement recursion in a language that doesn't necessarily support it natively.
