title: not able to set process.env.PORT variable in windows for node
body: <pre><code>const express = require('express'); 
  const api = express();
  
  api.get('/', (req, res) =&gt; res.send('Hello World'));
  
  var port = process.env.PORT || 3000;
  
  api.listen(port, () =&gt; console.log(`Listening to port 
  ${port}`));
  </code></pre>
  
  <p>I am using this command to
  set <code>PORT=5000</code>
  After setting it stills show Listening  to port 3000</p>
