Removing elements from JavaScript arrays

Question

I have the following array setup, i,e:

var myArray = new Array();

Using this array, I am creating a breadcrumb menu dynamically as the user add

I like this implementation of Array.remove, it basically abstracts the use of the splice function:

// Array Remove - By John Resig (MIT Licensed)
Array.prototype.remove = function(from, to) {
  var rest = this.slice((to || from) + 1 || this.length);
  this.length = from < 0 ? this.length + from : from;
  return this.push.apply(this, rest);
};

Usage:

// Remove the second item from the array
array.remove(1);
// Remove the second-to-last item from the array
array.remove(-2);
// Remove the second and third items from the array
array.remove(1,2);
// Remove the last and second-to-last items from the array
array.remove(-2,-1);
