The scope of a property: to me a very important addition to make - MOD EDIT - Check comments for the correct explanation

Please do not post posts like this in the Forum as they are misdirecting and can be confusing to new programmers. Thanks.

I am going to go through why you are wrong about the scope of these object key/value pairs though:

1) The following that you posted would not execute properly and does nothing. If you go into your JavaScript console, it will first say that a "Syntax Error" has occured: this is because It needs an "=" operator to assign the key of my_name to the object me. Next, when you try to run it, you will get a "Reference Error" because my_name does not exist. But if you reference me.my_name, you will find that does exist.

//Will not execute properly
var me {
     my_name: "Davide"
}
var key = my_name;
console.log(key);

Here is the proper form:

//Will execute properly
var me = {
     my_name: "Davide"
}
var key = me.my_name;
console.log(key);

2) Object and key pairs are unique to that specific object, given that the objects are not part of a prototype. If I create two objects such as "me" and "you" and give them both the key of "name", the "name" key is different in both objects because that key of "name" is unique to that object.

Also, since the "name" key is unique to those objects, you can even declare a variable named "name" and give it the value of "Bob" and you will see console.log print out the names: Marcus Davide Bob.

This means that the scope of the "name" key on each object is limited to that object.

You can run this code and prove that:

var me = {
    name: "Marcus"
  }
var you = {
    name: "Davide"
  }
var name = "Bob";
console.log(me.name);
console.log(you.name);
console.log(name);

3) You aren't initializing variables the correct way, so your code would not execute. If you notice in the above code block, I have the = operator in between var me and the { }. This is to assign the value(s) within the curly braces to the variable object.

4) In JavaScript, you can reference the values in both me and you just as you did. And you will get me.name is "Marcus" and you.name is "Davide" just as you would see if you execute the code I pasted for you.

5) If I were to make a prototype of a Person and then create me and you objects based on that prototype (and not specify a name key for them), they would both have the name given from the prototype until I specified a unique "name" key for each object. But since that is not the case here, we don't have to worry about that.
