title: Why is my Javascript increment operator (++) not working properly in my addOne function
body: <p>Please can someone explain to me why my addOne function doesn't work with the increment operator (++). Please see my code below.</p>
  
  <pre><code>// addOne Function
  
  function addOne(num){
    return num + 1
  }
  
  log(addOne(6)) =&gt; 7
  
  
  // same function with ++ operator
  
  function addOne(num){
    return num++
  }
  
  log(addOne(6)) =&gt; 6
  
  
  // Question - why am I getting 6 instead of 7 when I use ++ operator?
  </code></pre>
