Mapping object values from one object to another

I have an object called defaultOptions and a function that accepts as an argument an object called newValues meant to override the values in defaultOptions with its own. The values that are not specified in newValues should remain default.

var configOptions = {
    isActive: false,
    name: "",
    description: "",
    category: "",
    group: "default"
}

    publishOptions: function(newValues){
      $.each(newValues, function(key, value){
        if(configOptions.hasOwnProperty(key)){
          configOptions[key] = value;
        }
        else{
          configOptions[key] = value;
        }
      });
      console.log(configOptions);
    }

For example, if I use this method like so:

var myOptions = {
    name: "option one",
    category: "the best"
}

publishOptions(myOptions)

I would expect configOptions to look like this:

configOptions = {
    isActive: false,
    name: "option one",
    description: "",
    category: "the best",
    group: "default"
}

I'm using jQuery's each method to map the values from newValues to configOptions, but I suspect there is a much more succinct and elegant way to do this. I would appreciate any suggestions.
