Friends now I proceed onwards and here is the working code snippet and please use this carefully to avoid the mistakes:

1. Firstly, we need fresh reactjs setup and for that, we need to run below commands into out terminal and also we should have latest node version installed on our system and bootstrap as well:

npx create-react-app reactdemo

cd reactdemo

npm install bootstrap

npm i @popperjs/core

npm start

2. Finally for the main output, we need to add below code into our reactdemo/src/App.js file or if you have fresh setup then you can replace reactdemo/src/App.js file code with below code:

// 1. Import *useState* and *useEffect*
import React, {useState, useEffect} from 'react';
import "bootstrap/dist/css/bootstrap.min.css"

function App() {
    // 2. Create our *data* variable as well as the *setdata* function via useState
    // We're setting the default value of data to null, so that while we wait for the
    // fetch to complete, we dont attempt to render the data
  let [data, setdata] = useState(null)

    // 3. Create out useEffect function
  useEffect(() => {
    fetch("https://therichpost.com/testjsonapi/users/")
    .then(response => response.json())
        // 4. Setting *data* to the API DATA that we received from the response above
    .then(data => setdata(data))
  },[])

  return (
    <div className="App container py-5">
    
      <table class="table">
        <thead>
          <tr>
            <th scope="col">#ID</th>
            <th scope="col">Name</th>
            <th scope="col">Email</th>
            <th scope="col">Job Title</th>
          </tr>
        </thead>
        <tbody>
         
          {data && (data.map(item =>
            <tr>
              <th scope="row">{ item.id }</th>
              <td>{ item.name }</td>
              <td>{ item.email }</td>
              <td>{ item.job_title }</td>
            </tr>
            ))}
        </tbody>
      </table>
    </div>
  );
}

export default App;
