It is possible to define our own nonenumerable properties by using the Object.defineProperty function, which allows us to control the type of property we are creating.
Object.defineProperty(Object.prototype , "hiddenNonsense", {enumerable: false, value: "hi"}); for (var name in map) console.log(name); // → pizza // → touched tree console.log(map.hiddenNonsense); // → hi
