Replace push in array works but splice never called

Question

Having a Array like this:

var k =[1,2];
k.push(3);

redefine push like this:

function kPush(e){
  this[this.length] = e * 2;
}
Object.defineProperty(k, 'push', {
  get: function(){return kPush;}
});

And calling using

k.push(4);
document.write(k);

Gives:

 var k =[1,2]; k.push(3); function kPush(e){ this[this.length] = e * 2; } Object.defineProperty(k, 'push', { get: function(){return kPush;} }); k.push(4); document.write(k); 

Gives:

1,2,3,8

Everythings fine. Now I need to overwride splice but its never called.

Object.defineProperty(k, 'splice', {
  get: function(){return kSplice;}
});

But

console.debug(k.splice);

gives me function splice() { [native code] } . <-- its native? But i have overwritten the property!

How to overwrite splice ?

Answer 1

 var k =[1,2]; k.push(3); function kPush(e){ this[this.length] = e; } Object.defineProperty(k, 'push', { get: function(){return kPush;} }); Object.defineProperty(k, 'splice', { get: function(){return function(){ console.log("Splice"); Array.prototype.splice.apply(this,arguments); }} }); k.push(4); k.splice(1,1); document.write(k);
