global is an object containing any global variables (at least in Node.js, they're in window in the browser).
global是一个包含任何全局变量的对象（至少在Node.js中，它们位于浏览器的窗口中）。
Is there a similar variable that represents the current scope? Local variables don't show up in global (for a good reason :) )
是否有代表当前范围的类似变量？局部变量不会出现在全局中（有充分理由:)）
asdf = "hello";
var local = "hello";
console.log(global); // includes asdf
console.log(???); // includes local?

Is there an object represents the local scope?
Yes. There is.
是。有。
Could you access the object (directly)?
No. You can't.
不，你不能。
Why? JavaScript has only function scope - which is the execution Context. Within the execution Context, an Activation object(also known as call object) is used to create local variables as its property. However,
为什么？ JavaScript只有函数作用域 - 即执行Context。在执行Context中，Activation对象（也称为调用对象）用于创建局部变量作为其属性。然而，
...it is not a normal object as it has no prototype (at least not a defined prototype) and it cannot be directly referenced by javascript code.
...它不是一个普通的对象，因为它没有原型（至少没有定义的原型），它不能被javascript代码直接引用。
