(REACT JS) put value on 1 array element from compo…

I’m trying to give one component the array value at a certain index and assign a value that i want from the child component.

I want it like this because I’m trying to do a survey app and the number of question can be different. this is just a little test that concludes what I want.

the base Component

import React, { useState } from 'react';
import './style.css';
import Comp from './Component.js';
export default function App() {
  const [results, setResults] = useState([]);

  results.length = 20;
  results[3] = 'kiss';
  results[2] = [12, 454, 45];
  console.log(results);

  return (
    <div>
      <h1>Hello StackBlitz!</h1>
      <p>Start editing to see some magic happen :)</p>
      <Comp result={results[5]}/>
      <button onClick={() => console.log(results)}> SHOW </button>
    </div>
  );
}

the component

import React, { useState } from 'react';

 const Comp = ({result}) => {
  result = 1 
  console.log(result)
  return (
    <div>
      hhhhh
    </div>
  );
}

export default Comp

here is a place I set it up => https://stackblitz.com/edit/react-mfpk5f?file=src%2FApp.js,src%2FComponent.js

every suggestion is highly appreciated!
