remove an element from array

gistfile1.js

Array.prototype.remove = function(idx){
	var temp = new Array();
	var i = this.length;
	
	while(i > idx){
		var kk = this.pop();
		temp.push(kk);
	
		i--;
	}
	
	for(var i=temp.length - 2; i>=0; i--){
		this.push(temp[i]);
	}
}

// usage
var tArray = {"a", "b", "c"};
tArray.remove(2);
// result {"a","b"}

Array.prototype.remove = function(id){
return this.splice(id, 1);
