Leaflet filter on geoJson properties : multiple criteria

Question

I'm using Leaflet filter on geoJson data. I'm able to apply it with a simple criteria :

filter: function(feature, layer) {
     return feature.properties.field1 == "yes";
}

I can also apply two criteria with logical operators like && or || :

filter: function(feature, layer) {
     return (feature.properties.field1 == "yes" && feature.properties.field2 == "yes");
}

I want now to insert a condition (depending of a variable):

filter: function(feature, layer) {  
   if (varState == "01") {  
     return (feature.properties.field1 == "yes" && feature.properties.field2 == "yes");
   }
   else if (varState == "02") {
     return (feature.properties.field1 == "yes" && feature.properties.field2 == "no");
    }
    else {
      return feature.properties.field1 == "yes";            
    }
}

Does someone has already succeed this ?

Here is a full answer with a if ... else if ... else condition :

filter: function(feature, layer) {  
   if (varState == "01") {  
     return (feature.properties.field1 == "yes" && feature.properties.field2 == "yes");
   }
   else if (varState == "02") {
     return (feature.properties.field1 == "yes" && feature.properties.field2 == "no");
    }
    else {
      return feature.properties.field1 == "yes";            
    }
}
