理解 JS 中的函数表达式与函数声明 (YIXUNFE)
理解 JS 中的函数表达式与函数声明常用闭包的同学肯定很清楚下面一段代码:javascript//通常的闭包写法(function () { ...}())那么我们的问题来了,为什么要在 function () {...}() 之外用圆括号包裹呢?解答这个问题,就需要我们理解 Javascript 中函数表达式与函数声明的概念。 函数定义带来的错误虽然 function () {...} 看上去像是一个函数声明,但是由于没有函数名,它的本质其实是一个函数表达式。我们看下规范中对于函数声明与函数表达式的定义:...
javascript//通常的闭包写法(function () { ...}())
function () {...}()
function () {...}
