Question

I’m new to require/backbone developpment, and I what I’ve red two ways to write Views :

1st id :

define([
'jquery', 
'backbone',
'underscore'
], function($, Backbone, _){
    var View = Backbone.View.extend({
    ...
    });
    return View;
});

2nd is :

define([
'jquery', 
'backbone',
'underscore'
], function($, Backbone, _){
    var View = Backbone.View.extend({
    ...
    });
    return new View;
});

3rd is :

define([
'jquery', 
'backbone',
'underscore'
], function($, Backbone, _){
    var View = Backbone.View.extend({
    ...
    });
});

Is there someone explain me what’s the difference between those 3 way of writing views ?
Thanks a lot in advance.

Answer 1

The first example will return an object that you can instantiate, a class if you like.

var module = require('example1'),
myObject = new module();

The second will return what is essentially a singleton as subsequent calls to require will return the same object;

var myObject = require('example2');

The last wont return anything, I’m not 100% sure but I think its pretty useless.
