包含函数的对象文字表示法的执行速度是否比(全局范围）普通函数(取消引用）更快
Does object literal notation containing functions execute faster than (global scope) plain functions (dereferencing)?
请参阅：JavaScript Object Literal表示法与普通函数和性能含义？
我正在考虑将我的函数和相关数据转换为对象表示法。的性能成本（如果有的话）是多少
我目前在函数中使用了一种命名约定，它是结构化的，反映了将成为对象的内容。因此，对象文字表示法并没有真正为函数的目的添加太多说明。
无论如何，我计划转换为合适的对象。通过这样做，我会在执行速度方面获得或失去任何东西吗？（可能是由于取消引用？）
我正在考虑将以下函数和相关数据转换为对象表示法。我最终会得到以下对象：
o筛选器
oMenuImage
o计时器
o窗口
鼠标事件
o元素
o布局
o工具提示
因此，在查看a时，对象oFilter下面的第一个函数可能包含以下函数：
控制创建
商店
还原
重置动画
动画
旋转
设置旋转
调整大小
幻灯片样式切换
获取
设置
启用
播放

该网站是一个相当大的教育项目。在不久的将来，我将学习对象文字表示法（我喜欢）和框架的使用。以下是现有函数的列表（很大）：查找所有"函数fn"、隐藏、正则表达式、查找结果2、当前文档

正如T.J.Crowder在对"JavaScript对象文字符号与普通函数和性能影响？"问题的评论中所说：
JS中的Perf问题很棘手，因为引擎差异很大。但是如果你指的是问题中的两个选项，答案几乎是当然没有。一旦发动机有了函数引用，就执行两种情况下的调用都是一样的，所以我们必须看看引擎获取函数引用。
在第一个示例中，要调用foo，引擎必须在执行上下文的绑定对象。在第二个示例中，它具有以同样的方式查找Baz，然后在Baz上查找foo，这更重要步骤。但我敢打赌，这并没有真正的区别。
