javascript - 函数的[[Scope]]属性(Functions's [[Scope]] property)

Question

I have created a very simple example that will serve as an explanation to my question.

(我创建了一个非常简单的示例，它将作为对我的问题的解释。)

The code is pseudo-code, here it is:

(该代码是伪代码，在这里是：)

var scopePosition = "global";

function outer() {
    var scopePosition = "outer";
}

// debugger; We reached this line to inspect Execution Contexts and Function Objects
outer();

// Execution Contexts
var GlobalExecutionContext = {
    variableObject: {
        scopePosition: "global",
        outer: "pointer to function object called `outer`"
    },
    scopeChain: [GlobalExecutionContext.variableObject],
    this: {}
};

//Function Objects
var outerFunctionObject = {
    [[Scope]]: "pointer to GlobalExecutionContext or GlobalExecutionContext.variableObject or 
    GlobalExecutionContext.scopeChain ???"
};

The question itself is when the function gets created where does its [[Scope]] property points to exactly?

(问题本身是何时创建函数的[[Scope]]属性确切指向何处？)

Is it the Execution Context it was created or Execution Context Variable Object or Executions Context Scope Chain?

(是它创建的执行上下文还是执行上下文变量对象或执行上下文作用域链？)

My best guess would be GlobalExecutionContext.scopeChain, cause that way scope links won't be lost if we had a more nested function inside outer and the process is repeated.

(我最好的猜测是GlobalExecutionContext.scopeChain，这导致如果我们在外部内部有更多嵌套函数并且重复该过程，则不会丢失作用域链接。)
