index.js

import React, {createContext} from 'react';
import ReactDOM from 'react-dom';
import App from './App';


export const Context = createContext(null)
const arrayse={'id':1,'description':'desc'};
ReactDOM.render(
    <Context.Provider value={{
        arrayse:arrayse
    }}>
        <App />
    </Context.Provider>,
    document.getElementById('root')
);

app.js

import React from 'react';
import Shop from './pages/Shop'
function App() {
  return (
    <Shop/>

  )
}
export default App;

Shop.js

import React from 'react';
import ItemsList from '../components/itemsList';
function Shop() {
  return (
    <ItemsList/>
  );
}
export default Shop;

itemsList

import React,{useContext} from 'react';
import Item from './item';
import {Context} from "../index";
function ItemsList() {
  const {arrayse} = useContext(Context)
  return (
    <Item arrayse={arrayse}/>
  );
}

export default ItemsList;

item остается неизменным
