Questions about type Reference in ECMAScript.

[dSalieri]

When you read the specification, questions arise. I think people who also read this document in different versions also faced problems of not understanding some of the moments in this document.

Now I want to ask a couple of questions to clarify some moments related to the Reference type.

1. What data is of type Reference in the specification?
2. The specification says that: "The base value component is either undefined, an Object, a Boolean, a String, a Symbol, a Number, or an Environment Record". I would like to see examples of code with each base value. For example:

/// Definition variable in javascript code (example of javascript code)
var a;
/// Reference structure in engine
Reference = {
    Base: Environment Record, /// It's one of other cases
    ReferencedName: "a", 
    StrictReference: false
}

3. In the code, in the global code there is a variable bar (declared, bar - example of variable). We can address to it as window.bar orbar ... and here the most interesting. With window.bar what is base? And when bar? We know that declarations in the global code are the Object Records Environment, and if so, base will be appeal to the bar Records Environment. But appeal to the window.bar, base will be a window - type(Object). And here it is not clear. If this is an object environment, then why call through dot will be a window object, but not an object environment?
4. If inside of object we work with property object, the property of this object will have a Declarative Records Environment or Object Records Environment.
5. In the older specification, there was a note under the GetValue method. In the note we were talked about creating an object inside the [[Get]] method. Honestly, this note is in the latest versions of the specification, but the end was removed. In ECMAScript 5.1, this note reads as follows: "The only situation where such an actual property (What property is told about?) access is that of this internal method can have a visible effect is when it invokes (Who is invoker?) an accessor function". The most interesting in the last line. Which is "accessor function"? Where is placed? In internal method or outside (in user's object)? In general, this proposal is confusing. I would like to understand what exactly this sentence says.

@ndugger Really? Are you serious? Reputation on StackOverflow? Interesting idea but no. If you know about my questions - answer. Dont do flood.
P.S I do not need a reputation! I'll just leave a link to my question on the github!
