Javascript functional programming programmer's tool set and javascript tool set If you carefully read the sample code that has appeared so far, you will find that some of the methods here are unfamiliar. They are map (), filter (), and reduce () functions, which are crucial to functional programming in any language. Th

?? Functional programming in JavaScript main directory The fifth chapter of the category theory of functional programming in JavaScriptThomas Watson (then IBM chairman) said a famous word, "I think the world only five computer market." It was 1948, when everyone thought that computers would only be used for two things:

this method by adding a @xxx annotation to the method name. However, Java/c# 's annotation is also very daunting, too TMD complex, you want to play it, you need to know a bunch of annotation library documents, let people feel is learning another language. Python uses a very elegant method relative to decorator pattern and annotation, which does not require you to master any complex OO models or the various class library rules of annotation. It's all about the language level: a function-

The object nature of JavaScript's functional programming:function A (){var x= "Sth"; return B () {//do with X;}}var C = a ();equivalent tofunction A (){this.x = "Dosth";this.b = function () {//do with This.x}}var c = new A ();but1) Functional programming instinctively avoids the construction of useless objectsbecause function
