title: convert string value to Boolean (true or false)
body: <p>i.e. I have data like the below:</p>
  
  <pre><code>[{"id":"slz1","checked":"false"},{"id":"slz2","checked":"false"},{"id":"slz3","checked":"false"},{"id":"slz4","checked":"false"},{"id":"slz5","checked":"false"},{"id":"slz6","checked":"false"},{"id":"slz7",...........................}]
  </code></pre>
  
  <p>What is a good way find and convert my "<em>false</em>" to <code>false</code> for instance as I am needing a boolean <code>true</code> or <code>false</code> without quotes.</p>
  
  <p>I am getting the data like below:</p>
  
  <pre><code>  $.getJSON("./coolBeans.json", function(json) {
              data = json[key];
              console.log(data);         
     ...................
  </code></pre>
