Add a method to Array object in Javascript?

Question

Is it possible to add a method to an array() in javascript? (I know about prototypes, but I don\'t want to add a method to every array, just one in particular).

The

Answer 1

Arrays are objects, and can therefore hold properties such as methods:

var arr = [];
arr.methodName = function() { alert("Array method."); }

Answer 2

Yep, easy to do:

array = [];
array.foo = function(){console.log("in foo")}
array.foo();  //logs in foo

Answer 3

Just instantiate the array, create a new property, and assign a new anonymous function to the property.

var someArray = [];
var someArray.someMethod = function(){
    alert("Hello World!");
}

someArray.someMethod(); // should alert

Answer 4

var arr = [];
arr.methodName = function () {return 30;}
alert(arr.methodName);

Answer 5

function drawChart(){
{
    //...
    var importantVars = [list of important variables];
    importantVars.redraw = function(){
        //Put code from updateChart function here using "this"
        //in place of importantVars
    }
    return importantVars;
}

Doing it like this makes it so you can access the method directly after you receive it.
i.e.

var chart = drawChart();
chart.redraw();
