Marionette is an extension of Backbone that is very popular in building various JavaScript applications with a client-server system. It introduces a method for creating applications where you can define a class object that handles the entire application and acts as its root. 

You’ll learn the differences between views and templates. Next, you will cover displaying a model with a default value and use events to generate alerts. Then you’ll cover collectionView and CompositeView, to list contacts and display the column headers on the application’s main page, respectively. You will also learn to add routing to an application for quick navigation and implement web storage persistence. Then, you will learn how to add navigation and highlight menu items on the application’s main page.

This course will help you build highly interactive JavaScript applications as a web developer. It will further empower you to develop your applications by understanding Marionette.

**(True or False)** There's no need to worry about latency when dealing with remote data.


(True or False) There’s no need to worry about latency when dealing with remote data.

**(True or False)** Callbacks can be used to wait for the result of an asynchronous API before continuing processing.

(True or False) Callbacks can be used to wait for the result of an asynchronous API before continuing processing.

It's a promise of initiating work that is expected to happen in the future, and for which you can monitor progress in the meantime.


It's a promise of completing work that is expected to happen in the future and for which you can monitor progress in the meantime.

It's a promise of completing work that is triggered right away and for which you can monitor progress in the meantime.


At its core, what is a <code>promise</code>?

A ``Deferred`` object instance allows modifying/updating the internal request's status, while a `promise` can only read the request's status. 

A ``Deferred`` object instance allows creating and modifying the internal request's status, while a ``promise`` can only read the request's status. 

A ``Deferred`` object instance allows updating the internal request's status, while a ``promise`` can both read and modify the request's status. 

How are deferreds and promises different?

**(True or False)** It's possible to await the result of multiple promises simultaneously so that the maximal waiting time corresponds to the longest request, i.e., no extra time is spent waiting.

(True or False) It’s possible to await the result of multiple promises simultaneously so that the maximal waiting time corresponds to the longest request, i.e., no extra time is spent waiting.
