Discovering the identity of an item

Question

Discovering the identity of an item

Assume I have some JavaScript code like this:

Foo = {
    alpha: { Name: "Alpha", Description: "Ipso Lorem" },
    bravo: { Name: "Bravo", Description: "Nanu, Nanu" },
    delta: { Name: "Fly with me", Description: "Klaatu barata nikto" }
};

Table = [ Foo.alpha, Foo.bravo, Foo.delta];

x = Table[1];

Is there a way to extract the identifier bravo from x? While I could easily access x.Name or x.Description, my goal is to obtain the name in a different context without adding redundant identifiers. Any insights on solving this dilemma would be greatly appreciated.

My intuition suggests that it's not possible, but maybe someone out there knows a clever workaround.

    banana: { Name: "Banana", Description: "Alakazam" },
    cherry: { Name: "Cherry Bomb", Description: "Abracadabra" }
};

Table2 = [ ];
for(let value in Bar){
  let object = Bar[value];
  object = {...object , id:value }
  Table2.push(object)
}
y = Table2[1];
console.log(y)

If it were up to me, I would opt for using a Proxy ...

const _Bar = {
    apple: { Type: "Apple", Color: "Red" },
    banana: { Type: "Banana", Color: "Yellow" },
    cherry: { Type: "Cherry", Color: "Red" }
};
const Bar = new Proxy(_Bar, {
    get(target, key) {
        if (target.hasOwnProperty(key)) {
           return {...target[key], key};
        }
        return target[key];
    }
});
const Array = [ Bar.apple, Bar.banana, Bar.cherry ];
console.log(Array[0])
