title: What exactly does "variable initializer is redundant" mean?
body: <p>So I am using Webstorm IDE for some JavaScript and I believe it uses JSLint to inspect the code. I have a bunch of <code>variable initializer is redundant</code> warnings. I can't find anything about what it exactly means in terms of what I need to fix.</p>
  
  <p>Example:</p>
  
  <pre><code>function calcPayNow(){
      var payNowVal = 0;
      --snip---
      payNowVal = (Math.round(tec * x) - Math.round(allpmts * x)) / x;
     --snip--
  }
  </code></pre>
