Problem 1: All the data will be rendered after all api calls are completed
Problem 2: Possible issue of race condition on very fast load
Problem 3: Sometimes state can be replaced by wrong data (stale data)

Solution: Use Suspense & SuspenseList

```
import React, { Suspense, SuspenseList, useState } from "react";
import ReactDOM from "react-dom";

class UserController {
    private $input = array(
        2 => [
            'user_id' => 2,
            'user_name' => 'Mr. Abdul Kalam',
            'age' => 53,
        ]
    );
    private $user_id = 2;
