A better way to dynamically fetch nested object's value in javascript

Question

Here's my functtion

var getLocaleDefault = function(settings){
    var defaultLocale = settings.defaultLocale;
    eval('var locale = settings.locale.'+defaultLocale);
    return locale;
}

settings is a JSON.parse()ed object of a JSON

{

    "classes": 8,
    "config": "classConfig",
    "locale": {
        "en": "localeEn"
    },
    "defaultLocale": "en"
}

As the code is: I am trying to get object.locale.en just because defaultLocale is en. Is there a better way other than eval to achieve what i am trying to do? Or is it the best/effective way of doing these kind of works?

var locale = settings.locale[defaultLocale];
return locale;

Even better,

var getLocaleDefault = function(settings){
    return settings.locale[settings.defaultLocale];
}
