我可以限制Javascript的Array.prototype扩展的范围吗？

Question

I'd like to limit the scope of extending Array

Array.prototype.myExtension = function() { 
// do something;
// return something;
};

to the current JS module. This extension should be invisible in other modules.

Answer 1

The workarounds are to sandbox an Array in another scope (an iframe or web worker) or to define the method generically and call it (or apply ) with an array object.

modulenamespace.myExtension = function() { 
// do something;
// return something;
}


modulenamespace.myExtension.call(array)
