Me too, but ...

... a pascal-ish manner, should be:

var
  o: TJSObject;
begin
  o := TJSObject.new([
    'foo', 'bar',
    'object', TJSObject.new(['abc', 123]),
    'array', TJSArray.new(1,2,3)
  ]);
  Writeln(TJSJSON.stringify(o));
end.

or:

var
  o: TJSObject;
begin
  o := TJSObject.new(
    'foo', 'bar',
    'object', TJSObject.new('abc', 123),
    'array', TJSArray.new(1,2,3)
  );
  Writeln(TJSJSON.stringify(o));
end.

however, it seems not possible. Anyway, these syntax above are better than
the newObject()/newArray() ones. Another possibility (very verbose, but
...) would:

var
  o: TJSObject;
begin
  o := TJSObject.new(
    TJSPair.new('foo', 'bar',)
    TJSPair.new('object', TJSObject.new('abc', 123)),
    TJSPair.new('array', TJSArray.new(1,2,3))
  );
  Writeln(TJSJSON.stringify(o));
end.
