Recupera el valor de este objeto del servidor.
Si no se proporciona ninguna función de devolución de llamada, la solicitud se realiza de forma síncrona. Si se proporciona una devolución de llamada, la solicitud se realiza de forma asíncrona.
Se prefiere el modo asíncrono porque el modo síncrono detiene todo el otro código (por ejemplo, la IU del Editor de código de EE) mientras espera al servidor. Para realizar una solicitud asíncrona, se prefiere evaluate() en lugar de getInfo().
Devuelve el valor calculado de este objeto.
