title: how to set environment variable from terminal in windows
body: <p>I am following a node course and while setting the environment variable as shown it does not work</p>
  <p>It says to set environment variables, use <code>SET</code> on Windows and <code>EXPORT</code> on Mac:</p>
  <p><code>set jwtkey=myprivatekey</code>, when I use this nothing happens, it does not set anything.</p>
  <p>This is set using the config package, and I have also created a separate files for <code>default.json</code> and <code>custom-env.json</code></p>
  <pre><code>if (!config.get(&quot;jwtPrivateKey&quot;)) {
      console.error(&quot;FATAL ERROR: JwtKey Not Set&quot;);
      process.exit(1);
  }
  </code></pre>
  <p>please help</p>
  <p>this is my .env file(using dotenv)</p>
  <pre><code>PORT=9000 //this is working
  jwtPrivateKey=&quot;myPrivateKey&quot; //this is not working tho.
  </code></pre>
  <p>[basically, I wanted to hide my VERIFY SIGNATURE(digital signature) and store it in ENV so that it cant be accessed.]</p>
