built a awesome game by using reactJS

August 01, 2017

yesterday we made awesome game by using reactJS so I would like to share my experience \ ..............here we go

before that
we must setup for reactJs environment

It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production.
~~if you want try you follow my command~~
open your terminal
and

             npm install -g create-react-app
             create-react-app my-app

             cd my-app
             npm start

sucessfully we made setup our developement enviroment

and we create a folder structure like this

`in index.html code like this`

if you want to make different UI you can change or edit your edits in index.html

<!doctype html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="theme-color" content="#000000">
     <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
     <link href="css/bootstrap.css" rel="stylesheet">
        <title>React App</title>
</head>
<body>
    <nav class="navbar navbar-default">
            <div class="container-fluid" style="box-shadow: 0 0 5px black">
                <div class="container-fluid">
                    
                    </div>
                    
                        <ul class="nav navbar-nav navbar-right">
                          <img src="logo-tty.png">
                        </ul>
                    </div>
                    
                </div>
            </div>
            
        </nav>
    <noscript>
      You need to enable JavaScript to run this app.
    </noscript>
    <div id="root"></div>
   </body>
</html>

and index.js codes are

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';

function Square(props) {
return (
    <button className="square" onClick={props.onClick}>
      {props.value}

        value={this.props.squares[i]}

      />
    );
