The ajax call is asynchronous. You have to handle the promise callback

      value = 1;
      wher = "a = 1";
      var currentrec = [];
    function validate() {
         return $.ajax({
         url: 'validate.php',
         type: 'post',
         dataType: 'json',
         data: {'method': "get_unit_lesson", 
         'value': value,
         'wher': wher,
         'tbl': "geography_prep_3"},
         success: function (data) {
        currentrec = data;
        },
        });
    }

    var successful = validate();
    successful.done(function(){

        var dd = [];
        for (var s = 0; 0 < currentrec.length; s++) {
        dd = currentrec["unit"]}


        var game; 
    });
