Unable to use native javascript Array functions in phonegap

I've got to the point where I have started using Array functions inside of my Phonegap app.

I am running KickCat 4.4.2 with my Nexus 5, my Nexus 4 also suffers from the same problem.

But to my shock horror it seems that which ever browser phonegap is using it does not have any of the array functions defined. 

Array()
 []
Array.reverse
 undefined
Array.join
 undefined
Array.push
 undefined

So Array is a function, but anything more does not exist.

Is there anyway to active or use these functions?

The actual function I'm after is Array.reverse.

Uncaught TypeError: Object function Array() {[native code]} has no method 'reverse' when running Array.reverse(Object.keys(data))

If you'd like to reverse the collection returned by Object.keys(), the collection will be an Array so you can simply chain the call to .reverse():

var reversedKeys = Object.keys(data).reverse();

The error is because Array.reverse() doesn't exist and typically won't. The standard Array methods are actually defined as properties of Array.prototype rather than as properties of Array itself.

Though, you can define it so it's available from both:

Array.reverse = function (collection) {
    return Array.prototype.reverse.call(collection);
};

var reversedKeys = Array.reverse(Object.keys(data));
