title: Dynamically generating a function name based on a variable
body: <p>What I want is to create a function whose name will come from the content of one of my variables.</p>
  
  <p>Example :</p>
  
  <pre><code>var myFunctionName = "tryAgain";`
  
             [tryAgain]
                 |
                 |
                 |
  function myFunctionName() {
      alert('Try Again !');
  };
  </code></pre>
