JavaScript中的快捷方式融合优化 [英] Shortcut fusion optimization in javascript

问题描述

我听说lodash和其他javascript库使用一种称为快捷键融合"的技术进行优化，但是找不到任何对该技术的详细说明.

I have heard that lodash and other javascript libraries use a technique called 'shortcut fusion' for optimization but couldn't find a detailed explanation of the technique anywhere.

任何人都可以提供链接或以示例方式解释捷径融合"的含义吗?

Can anyone provide a link or explain with an example what 'shortcut fusion' means?

推荐答案

一个简短而不清楚的解释- https: //wiki.haskell.org/Short_cut_fusion

For a very short and unclear explanation - https://wiki.haskell.org/Short_cut_fusion

即使对于Haskell，我仍然找不到详细的解释.我能找到的最接近详细的解释是在书的一章中- http://link.springer.com/chapter/10.1007%2F978-3-642-32037-8_12#page-1

I still couldn't find a detailed explanation, even for Haskell. The closest to detailed explanation i could find was in a chapter in a book - http://link.springer.com/chapter/10.1007%2F978-3-642-32037-8_12#page-1

本章以pdf格式免费提供- http://www .fing.edu.uy/〜pardo/papers/tfp2011.pdf

The chapter is available for free as a pdf - http://www.fing.edu.uy/~pardo/papers/tfp2011.pdf

这看起来像是学术论文的兔子洞. 捷径融合"上最有用的链接是有关超级怪异/数学学术论文的.比我在这里可以咀嚼的要多得多.

This looks like a rabbit hole of academic papers. Most useful links on 'shortcut fusion' are for super geeky/mathematical academic papers. Bit much more than i can chew here.

P.S. -当我找到它们时，将继续用更多详细信息更新此答案.

P.S. - Will keep updating this answer with more details as i find them.
