title: get value from key in sessionStorage javascript
body: <p>Is it possible to check if a specific value exists in a key in sessionStorage?</p>
  
  <p>Let's say that I have a key that is named "item" and I got digits in that key. I want to check if the digit "5" exists in item. </p>
  
  <p>I have tested to write like this:</p>
  
  <pre><code>  if(sessionStorage.getItem("item") == "5");
  </code></pre>
  
  <p>but It doesn't respond as i want.</p>
  
  <p>Is there another way I can check if the digit 5 exists in item?</p>
