Unable to correctly concatenate a string variable
Programming Languages

I have been to recreate a problem that I am having with strings with
the trivial code snippet given below. In the trivial code example, I
am reading five lines from a data file, each line having only one word.
I try to concatenate each word read into a string variable, separated

<p>Enter names in the fields, then click "Submit" to submit the

 <form name="form">

<input type="text" id="currentDate">

</form>
<script>

function test() {


  var birthDate = document.getElementById("birthDate");

  var currentDate = document.getElementById("currentDate");




  var ageDate = birthDate.value - currentDate.value;


  function ageD(ageDate) {
    if (ageDate < 1) {
      return function calculate(y) {
        Math.abs(ageDate) = y
      }
    } else {
      return function calculate(y) {
        ageDate = y
      }
    }
  }
  var ageDale = ageD();
  var x = ageDale(ageDate);



  alert(x)
}

</script>

</body>
</html>

I can't seem to fix this. I keep getting undefined for x, its probably something simple, but i appreciate the help.

It might have something to do with my functions, because i didnt really know what i was doing when i set them up.
