Pas2JS pascal source code


var
  a: array of Integer;
begin
  a := [1] + [2, 3] + [4];
  Writeln(a.Map(IntToStr).Join(','));  // 1,2,3,4 

  a := a + [5, 6];
  Writeln(a.Map(IntToStr).Join(','));  // 1,2,3,4,5,6

  a := [0] + a;
  Writeln(a.Map(IntToStr).Join(','));  // 0,1,2,3,4,5,6


      var a = [];
      a = [1].concat([2, 3], [4]);
      WriteLn((a.map(IntToStr)).join(","));
      
	  a = a.concat([5, 6]);
      WriteLn((a.map(IntToStr)).join(","));
      
	  a = [0].concat(a);
      WriteLn((a.map(IntToStr)).join(","));
