title: if(process.env.NODE_ENV === 'production') always false
body: <p>When trying to build an angular-webpack application by running the build command from this scripts list on the package.json:</p>
  
  <pre><code>"scripts": {
      "test": "NODE_ENV=test karma start",
      "build":  "if exist dist rd /s /q dist &amp;&amp; mkdir dist &amp;&amp; set NODE_ENV=production &amp;&amp; webpack &amp;&amp; cp app/index.html dist/index.html",
      "start": "webpack-dev-server --content-base app"
    },
  </code></pre>
  
  <p>this is the result on the console : </p>
  
  <pre><code>$ npm run build
  
      &gt; webpack-ng-egg@1.0.0 build M:\Learning webpack\egghead.io - AngularJS - Angula
      r and Webpack for Modular Applications\webpack-ng-egg
      &gt; if exist dist rd /s /q dist &amp;&amp; mkdir dist &amp;&amp; set NODE_ENV='production' &amp;&amp; webp
      ack &amp;&amp; cp app/index.html dist/index.html
  
      process.env.NODE_ENV  : 'production'
      process.env.NODE_ENV === 'production' ????  : false

  <p>this is how looks like the webpack.config.js file :</p>
  
  <pre><code> var webpack = require('webpack');
      var path = require('path');
      var config = {
          context: path.resolve(__dirname, "app"),

          output: {
              path : __dirname + '/app',
              filename:'bundle.js' // il ne sera pas généré dans le code, juste en mémoire
          },
          plugins:[

          module:{
              loaders: [
              {
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel', // 'babel-loader' is also a legal name to reference
                query: {
                  presets: ['es2015']
                }

          },
          devServer:{
              //contentBase:path.join(__dirname, 'dist') // ceci est juste un exemple, si dist est l'endroit ou on aurait généré les fichiers
              inline:true, // les mises à jour de style ne sont plus affichés instantnément avec cette option donc j'ai ajouté le watch:true et çà marché!!!

      if(process.env.NODE_ENV === 'production') {
          console.log("this is the prod env!!!!!!!!!!");

      }
  
      module.exports = config;
  </code></pre>
  
  <p>the problem here is that when testing <code>(process.env.NODE_ENV === 'production')</code> it never returns true even that it's supposed to be (see what is logged on the console above). I have tried to chage to a simple equality instead the strict one but still get false all the time.</p>
