如何编写内置原型的替代品？

Question

I'm using a Javascript interpreter which seems to provide a buggy Array.prototype.sort and I'd like to replace it (at least for test purposes).

I've got a function mySort(array, comparator) , but how can I make it to a function working like array.sort(comparator) ?

I also need to provide a default comparator, does a simple return a<b ? -1 : a>b ? +1 : 0 return a<b ? -1 : a>b ? +1 : 0 return a<b ? -1 : a>b ? +1 : 0 suffice?

And there may be more problems I'm unaware of?

A side question: My simple sorting works, but I'd gladly replace it by some well tested code.

Answer 1

Array.prototype.sort=function(comp){ return mySort(this,comp);};

Or using custom arrays:

myArray=Object.create(Array.prototype);
myArray.sort=function(comp){ return mySort(this,comp);};

example=Object.create(myArray);
example.push(1,2);
example.sort();
