  Presenter: Padmalochan, MindfireSolutions What is Backbone js? Backbone.js gives structure to web applications by providing Models with key-value binding and custom events,Collections with a rich API of enumerable functions,Views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. http://backbonejs.org/

  Presenter: Padmalochan, MindfireSolutions Why to use Backbone  It encourages you to abstract your data into models and your DOM manipulation into views and bind the two together using events.  Need to Build complex UI in Browser.  No More jQuery,no need to store data in DOM, store data in models instead event binding just works.  If what you plan to build is something where the UI regularly changes how it displays but does not go to the server to get entire new pages then you probably need something like Backbone.js.  Provides a structure into client side application

  Presenter: Padmalochan, MindfireSolutions Architecture Pros : 1. Fast 2. Highly Interactive. 3. Scalable Cons: 1. SEO problem (can't index) 2. Difficult to test 3. Security issues. 1. Routers 2. Models 3. Collection 4. Views

  Presenter: Padmalochan, MindfireSolutions Models  Models are the heart of any JavaScript application, containing the interactive data as well as a large part of the logic surrounding it: conversions, validations, computed properties, and access control.  Communicate to View through events.  Provide LifeCycle.  Read attribute with get method and write with set method.  Validation – Validate & isValid  Model Identity  Defaults,initialize.  Backbone.Model vs Backbone.Model.extend  Model have save,fetch and destroy methods for synchronizing with the server
• 11.
  Presenter: Padmalochan, MindfireSolutions Collection  Collections group of related model.  Fetch model from server.  Create them and save them back.  Array like object.
• 12.
  Presenter: Padmalochan, MindfireSolutions Views  The general idea is to organize your interface into logical views, backed by models, each of which can be updated independently when the model changes, without having to redraw the page  Handles Model events as well as DOM events.  All views have associated el property.  $el is a Jquery wrapper.  Every view maps to exact one DOM element  Render the UI as you see fit.  Declarative syntax to register handlers for DOM elements.
• 13.
  Presenter: Padmalochan, MindfireSolutions Templating  Underscore.js Template.  Client-side templatating.Templating happens in views render method.  Dynamically build markup from template and some data.  Backbone doesn't have its own templating engine. Underscore Templates  <%.... %> - execute arbitary code.  <% ...%> - evaluate an expression and render in result inline.  <% ...%> - evaluate an expression and render html escaped in result inline.
