created by the literal amount. You can assign properties to variables, arrays, or other objects. Can be passed as a parameter to a function. Can be returned as a function's return value. You can have properties that are dynamically created and assigned values. 命名一个函数时，该名称在整个函数声明范围内是有效的。如果函数声明在顶层，window对象上的同名属性则会引用到该函数。 所有的函数都有一个name属性，该属性保存的是该函数名称的字符串。匿名函数的name属性值为空。 在JavaScript中，作用域是由function进行声明的，而不是代码块。声明的作用域创建于代码

This article mainly introduces a simple JavaScript framework, which helps beginners understand the creation and Inheritance of JS classes. If you need it, refer to the following when writing the work-in-progress JavaScript book, I spent quite some time on the javascript inheritance system and studied various methods to simulate classic inheritance. Among these te

JavaScript handles scope and how varous JavaScript libraries provide methods for dealing with it and how they smooth out a few bumps. we'll also look at how you can get back to basics and do some interesting scope wrangling without a library, a useful approach if you're writing code that needs to stand alone. Learning advanced JavascriptA very nice tutorial to learn

The JavaScript language itself does not provide a class, and there is no class inheritance mechanism for other languages, its inheritance is implemented through the object's prototype, but this does not meet the requirements of the COCOS2D-JS engine. Since the COCOS2D-JS engine evolved from cocos2d-x, almost all of the APIs in the early versions of Cocos2d-js cocos2d-html were designed to emulate the Cocos2d-x API, and Cocos2d-x itself was written in

JavaScript Learning-Closures 1. What is closuresIn most books, closures are defined as "closures refer to functions that have access to variables in another function scope." ”。 The concept is too abstract to be helpful to beginners. Fortunately, the JavaScript Ninja Cheats 5.1 gives an example to further explain what a closure is: varOutervalue= '

I want to extract the essence of inheritance technology to a simple, reusable, easy to understand, and without any dependencies. In addition, I want to make this result simple and very useful. Here is an example of the effect I want: varPersonClass. extend ({init:...

This article and we share the main is the refinement of JavaScript closure to implement function overloading related content, come to see it, I hope to everyoneLearn JavaScripthelpful. 1. Preparation of Knowledge1.1 Closuresa closure is a scope that a function creates when it is created, allowing the function to access and manipulate variables other than the self function. Closures allow a function to access all variables and functions that exist with

Douglas Crockford points out that JavaScript is the most misunderstood programming language in the world. Because JavaScript lacks common object-oriented concepts, many program apes believe that JavaScript is not a suitable language. When I was working on my first JavaScript project, I also found that I couldn't put my

The JavaScript language itself does not provide a class, there is no other language class inheritance mechanism, its inheritance through the object's prototype implementation, but this does not meet our requirements for the COCOS2D-JS engine, all classes are directly or indirectly inherited implementation.var person = class.extend ({ //Declaring a person class, inheriting from Class,class.extend () means inheriting from class Init:function (isdanci
