title: Is it possible in Javascript to get the name of a variable?
body: <p>I know this is completely useless, but I'm nonetheless curious. Is it possible to do something like the below? </p>
  
  <pre><code>function getVariableName ( v )
  {
      // .... do something ..... 
      // return the string "v" 
  }
  var x = 69;
  var y = "somestring";
  console.log(getVariableName(x)); // prints "x" to the console
  console.log(getVariableName(y)); // prints "y" to the console
  </code></pre>
