title: Increment localStorage value by one
body: <p>I am working on an attempted log in feature to our application. They fail three times it kicks them out altogether. To keep count of how many times they attempt I thought I would use localStorage because I can easily manipulate it. However, I am having trouble incrementing the value when they fail to authenticate themselves.</p>
  
  <p>At the top, I am setting the localStorage variable</p>
  
  <pre><code>localStorage.setItem("attempts", "0")
  </code></pre>
  
  <p>and then if the server returns an error, I am trying to increment that value.</p>
  
  <pre><code>if(errorCode === 4936){
    var attempts = localStorage.getItem("attempts");
    localStorage.setItem(attempts++);
    console.log(attempts);
  }
  </code></pre>
  
  <p>and obviously this is not working, but all I can find when I research is setting and getting the localStorage nothing about updating or changing. Any help would be wonderful!</p>
