title: How to slice a number in JavaScript?
body: <p>I've the following code snippet,</p>
  <pre><code>var code = 895804220010013030;
  var last = code.slice(-2);
  var n = last.includes(00, 01, 10, 11, 20, 21, 30, 31 );
  
  if (n===true) {
    alert(n)
  } else {
   alert('false')
  }
  </code></pre>
  <p>But it invokes syntax error, the only way it works well is to put the quotes to the numbers</p>
  <pre><code>var code = 895804220010013030;
  </code></pre>
  <p>but I need to run it without putting the quotes.</p>
