I was learning destructuring and got stuck when both the key and value of the object are strings.

This is the `App.js` and here I am destructuring the object, I am getting a syntax error.

I have commented the line where I am getting an error

```
import "./styles.css";
const info = {
  name: "Ankit Singh Chauhan", 
  standard : 12 , 
  subjects : {
    sub1 : "Maths" , 
    sub2 : "Science" , 
    sub3 :{
      "sub3.1" : "ballleballe" , 
      "sub3.2" : "AdvancePhysics",
    }
  }
}
export default function App() {
  const {name ,standard ,subjects} = info ;
  const {sub1 , sub2 , sub3} =  subjects;
  // const { "sub3.1" , "sub3.2"} = sub3 ; 
  return (
      <>
      <div>
        <h3> Hi my name is {name} and I study in class {standard} my favourite subjects are 
           {sub1} and {sub2}</h3>  
        <h1> And the advance one are {sub3["sub3.1"]} and {sub3.["sub3.2"]}  </h1>     
      </div>
      </> 
  );
}

```

Can you suggest me some edits?
