It turns out,

Symbol()
Object.assign()
Proxy

all of them are not nessary to implement Reflection (computer programming) at least for this topic.

See my code below:

const isPrimitive = val => (val !== Object(val));

const toObj = p => !isPrimitive(p)
  ? p //object return
  : (typeof (p) === "boolean")
    ? new Boolean(p)
    : (typeof (p) === "number")
      ? new Number(p)
      : (typeof (p) === "string")
        ? new String(p)
        : p; //Symbol()

console.log(toObj(true));
console.log(toObj(7));
console.log(toObj("hello"));

const selfAware = i => i[i] = i;
const isAware = i => (i[i] === i);

const I = i => (i === I) || (i == null)
  ? i
  : selfAware(toObj(i));

const isI = i => (i === I)
  ? true
  : (i == null)
    ? false
    : isAware(i);

const ss = I(6);

console.log(ss);

console.log(ss[ss]);
//self-similarity
console.log(ss[ss][ss]);


const obj1 = {
  a: 2
};
const obj2 = I(obj1);
console.log(obj1);
console.log(obj2);

console.log(
  I("Hello world!").toString() //Yes, it works!
);

console.log(I(1) + I(2)); //3

console.log(
  (I) //[Function: I]
);
console.log(
  (I)(I) //[Function: I]
);
console.log(
  (I)(I)(I) //[Function: I]
);
console.log(
  (I)(I)(I)(I) //[Function: I]
);
console.log("============================");


console.log(
  isI(I) //true
  , isI(1) // false
  , isI([]) // false
  , isI({}) // false
  , isI(x => x) // false
  , isI(true) // false
  , isI(false) // false
  , isI(undefined) // false
  , isI(null) // false
);

console.log(
  isI(I(I)) // true
  , isI(I(1)) // true
  , isI(I([])) // true
  , isI(I({})) // true
  , isI(I(x => x)) // true
  , isI(I(true)) // true
  , isI(I(false)) // true
  , isI(I(undefined)) // false
  , isI(I(null)) // false
);
