title: While loop decrements in JavaScript until it reaches 0 and prints "Blastoff"
body: <p><strong>Exercise:</strong></p>
  <p>Declare a variable named countdown and assign it the value of 10. In a <em>while</em> loop, decrement the value of countdown once for every iteration and print it. Once countdown hits 0, print 'Blastoff' to the console.</p>
  <p><strong>What I've done so far:</strong></p>
  <pre><code>var countdown = 10;{
      while (countdown &gt; 0 || 0=== &quot;Blastoff!&quot;){
          console.log(countdown);
          countdown = countdown - 1;
      }
      console.log(&quot;Blastoff!&quot;);
  }
  </code></pre>
  <p>This is the result until now that i thought it should be correct:</p>
  <pre class="lang-none prettyprint-override"><code>Output
  &gt;&gt;&gt;&gt;Code is incorrect
  The first line in your while's block should decrement the value of the variable countdown
