I have downloaded the npm i --save esri-loader @esri/react-arcgis but why is it i cant load the map? did i miss something?

import React from 'react';
import Map from '../../component/Map/Map.js'
const HomePage = () => {
  return (
    <div>
      <Map/>
    </div>
  );
};

export default HomePage;

component/Map/Map.js

import React , {useRef,useEffect} from 'react';
import {loadModules} from "esri-loader";


function Map() {
    const MapElement=useRef(null)
    useEffect(()=>{
        let view;

    loadModules(["esri/views/MapView", "esri/WebMap"],{
        css:true
    }).then(([MapView, WebMap])=>{
        const webmap= new WebMap({
            basemap:'topo-vector'
        })
        view = new MapView({
            map:webmap,
            center:[],
            zoom:8,
            container:MapElement.current
        })
    })
    return()=>{
        if(!!view){
            view.destroy()
            view=null
        }
    }
    })
    return (
        <div style={{height:800}} ref={MapElement}>

Hi@mursalahmed if you are starting a new project with React and using local builds, then we recommend using our ES modules (@arcgis/core) instead of the AMD modules that are injected using the esri-loader library. Here is an example repository: https://github.com/Esri/jsapi-resources/tree/master/esm-samples/jsapi-create-react-app.

You can learn more about the differences between the modules here: https://developers.arcgis.com/javascript/latest/tooling-intro/.
