javascript - 2 ways of defining array

Question

i have some array, and inside array i want to define another array. Are those 2 definitions equal? many thanks :)

args: [{
    key: "data",
    ajaxOptions: {
        url: '/rest/adrestresource/1.0/activedirectory/findgroups%[email protected]%20Bezhesla1%20localhost%20CN=Builtin,DC=lab,DC=local',
        type: "GET",
        dataType: "xml"
    }
}];

args: function () {
    return [{
        key: "data",
        ajaxOptions: {
            url: '/rest/adrestresource/1.0/activedirectory/findgroups%[email protected]%20Bezhesla1%20localhost%20CN=Builtin,DC=lab,DC=local',
            type: "GET",
            dataType: "xml"
        }
    }];
}

It is used for configuring a gadget, documentation says: Either an array of objects or a function that returns one. T First approach is working correctly, but defining array by function returning it is not working :?

You want to use getters and setters: developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/… — simonzack

That's confusing documentation, if it accepts function then it means exactly what you are doing. And calling args: function(){return ['blah']}() is really not passing a function. it's passing a value that the function returns. — maulik13

The first example you have a property that is an array. The second example, it is a method that returns an array, so call it like:

// example 1
var myArray = Something.args; // property

// example 2
var myArray = Something.args(); // method

It could be args: (function () {return[]})() to return an array
