在对象中声明函数名，为什么？ [英] declare function name in object, Why?

问题描述

正在研究一些js代码性能并看到了这种方法：

Was working on some js code performance and saw this approach:

window.sample = {

    foo: function foo(a,b){
       // code goes here
    }

    bar: function bar(a,b){
       // code goes here
    }

}

有什么理由吗为什么你会在函数一词之后减速函数名？

is there any reason why you would decelerate the function name after the word "function" ?

它有助于调试吗？

是好还是坏或只是不必要？

is it good or bad or just unnecessary?

推荐答案

而不是为foo和bar属性分配匿名函数，它们正在分配命名函数。

instead of assigning an anonymous function to the foo and bar properties, they are assigning named functions.

它可能有助于调试：我知道的唯一区别是你会看到函数的名称显示在调用堆栈中而不是javascript匿名函数

it can be helpful for debugging: the only difference this makes, that i know of, is that you will see the names of the functions show up in the call stack instead of "javascript anonymous function"
