react project setup - npm run webpack issue

I am following http://ccoenraets.github.io/es6-tutorial-react/setup/ for react project setup. In the end part, I am getting this error after running 

npm run webpack

Error I am getting - 

npm run webpack

> [email protected] webpack /home/rishi/Desktop/project-newborn
> webpack

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.module has an unknown property 'loaders'. These properties are valid:
   object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, noParse?, rules?, defaultRules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, unsafeCache?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp?, strictExportPresence?, strictThisContextOnImports? }
   -> Options affecting the normal modules (`NormalModuleFactory`).

When using Webpack 4 you must use rules instead of loaders and it's better to use use instead of loader.

 var path = require('path');
 var webpack = require('webpack');

 module.exports = {
     entry: './js/app.js',
     output: {
         path: path.resolve(__dirname, 'build'),
         filename: 'app.bundle.js'
     },
     module: {
         rules: [
             {
                 test: /\.js$/,
                 use: [
                     {
                         loader: 'babel-loader',
                         options: {
                             presets: ['es2015', 'react'],
                         },
                     },
                 ],
             }
         ]
     },
     stats: {
         colors: true
     },
     devtool: 'source-map'
 };
