// type TCell = class end;
 //      TCellIterator = class public procedure Reset; end;
 // 
 // function IFF(condition : boolean; const c1, c2 : TCell) : TCell; 
 // function IFF(condition : boolean; i1, i2 : integer) : integer;

and applied the IFF function

 // procedure TCellIterator.Reset;
 // var i : integer;
 // begin                          
 //   i := IFF(3 > 0, 0, -1);
 // end;

The JS output is 

 // cells_tcelliterator.$p.reset = function()
 // {
 //    var $t = this, i;
 //    i = (3 > 0, 0, -1); // (*)
 // };
