Buzzer on ESP8266 (NodeMCU Amica)

Hello,

Does anyone have working examples with passive buzzer?
Because when I try this:

analogWrite(A0, 0.5, { freq: 1000 } );

I have such message:

>Uncaught ReferenceError: "A0" is not defined
 at line 1 col 13
analogWrite(A0, 0.5, { freq: 1000 } );

I've also tried digital pins, but no sound in result(and no error).

Could anyone show working example? (https://www.espruino.com/Making+Music doesn't work for me)

Thanks
