title: String case conversion javascript
body: <p>So I really need help with something thats been bugging me for some time now. I have a function which looks like this:</p>
  
  <pre><code>var convertString = function (str){
  
  // Place for additional code here.
  
  return str;};
  </code></pre>
  
  <p>And what I need this function to do is to convert the string that comes with str.</p>
  
  <p>Example: I need the scentence "I really LOVE JavaScript" to be converted to "i RE#LLY love j#V#sCRIPT"</p>
