原创关于add(2)(3)(4)的记录

最近在读汤姆大叔的系列博文，看到这样一道题，记录下解题过程题目：实现如下语法的功能：var a = add(2)(3)(4); //9 很显然，要通过闭包来保存中间计算的结果，并通过返回函数进行级联操作，这个返回的函数还应该是一个自引用函数。由于之前在别的地方看到过类似的题目，记得同时要求满足add(2，3)(4)这样的调用，于是做了下处理。Ilet ad

原创 proto和prototype

提到javascript，不得不说到原型链：当在自身找不到某个属性时，则会到上一层原型查找，通过此机制可以实现继承。 1，表面的prototype，隐藏的__proto__先看简单的原型链：这里的a自身没有定义toString方法，但是通过到Object.prototype（原型链的顶层）上找到toString方法，从而正确的输出了。那a是通过哪个属性追查到Object....

原创 js的函数作用域跟块级作用域

一，js中的作用域 js中除了全局作用域，还有函数作用域。嗯，还有块级作用域。二，函数作用域跟块级作用域的区别当将代码看成一个IIFE时，全局作用域其实就是一个函数作用域。那么函数作用域跟块级作用域的区别是什么呢？函数作用域：变量在定义的函数内及嵌套的子函数内处处可见；块级函数域：变量在离开定义的块级

原创初识commonjs

一，为什么要用commonjs 在大型项目中，需要根据需求和功能将程序划分为不同的模块。第一有利于多人开发，提高开发效率；第二提高了模块的复用率，清晰明确的框架也能提高程序的可维护性和健壮性。但是多人开发也会带来一些问题。依赖问题：不同的模块之间可能存在依赖问题，如果需要手动指定其加载次序，不仅浪费人力物力，也不利于修改
