title: Why is my comparison not producing the expected result?
body: <p>I'm expecting this to output "Failed" but instead it outputs "Excellent", even though the value being compared doesn't match that comparison.</p>
  
  <p>What's wrong with my code?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>let grade = 99;
  if(140 &lt;= grade &lt;= 150) {
    console.log('Excellent');
  }
  else if(100 &lt;= grade) {
    console.log('Very Good');
  }
  else if(grade &lt; 100) {
    console.log('Failed');
  }</code></pre>
