Initial URL 

                                

                                                            

                                    

                                        

                                        Initial Description
                                        

                                    

                                    
This will check if object is an array object.

This will add isArray() method to Array native object. Can be used to check if passed in object is an array. Future ecmascript 5 will have this included. Can use this in the meantime.

Using instanceof Array does not work in certain versions of IE.

e.g.

var arr = [1,2,3];

alert(Array.isArray(arr)); //displays as true
