WebReference.com wrote an article about this in their Array Power series.
Part 1 covers background information and shift()/unshift():

Part 2 provides push()/pop():
http://www.webreference.com/dhtml/column32/
Part 3 finally has the splice() method:

I'm the guilty one...
// Returns a new trimmed string
// 'side' is which side to trim. Can be "left", "right" or "both" (default)
String.prototype.trim = function(side) {
switch(side) {
case "left":
return this.replace(/^\s+/, "");
case "right":
return this.replace(/\s+$/, "");
default:
return this.replace(/^\s+|\s+$/g, "");
}
}
// These class functions don't require 'str' to be strings as the toString() method is
called
String.Trim = function(str) { return str.toString().trim(); }
String.LTrim = function(str) { return str.toString().trim("left"); }
String.RTrim = function(str) { return str.toString().trim("right"); }
// These are for VBScript-feeling
function Trim(str) { return str.toString().trim(); }
function LTrim(str) { return str.toString().trim("left"); }
function RTrim(str) { return str.toString().trim("right"); }
