Function currying
-----------------

Sample javascript code for currying
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: javascript

  function searchStudent(studentList, studentName) {
    for(var i=0; l = studentList.length; i<l; i++) {
      if(studentList[i].name==studentName) {
        return studentList[i];
      }
    }
    return null;
  }

  searchStudent(list, "Saurabh");
  searchStudent(list, "Kahlil");
  searchStudent(list, "Aatish");


  function searchStudentInList(studentList) {
    return function(studentName) {
      return searchStudent(studentList, studentName);
    }
  }

  var studentSearcher = searchStudentInList(list);
  studentSearcher("Saurabh");
  studentSearcher("Kahlil");
  studentSearcher("Aatish");
