DESCRIPTION
Ember.js is a new JavaScript framework for building ambitiously complex web applications. Taking lessons from the iOS development platform and other JavaScript frameworks that came before it, Ember embraces the idea that our applications are more alike than they are dissimilar. It encourages coding by convention, testing, and MVC patterns. Building an app on Parse makes your data available via the Parse REST API. Using that API, ember-cli and Ember-Data, I’ll show you how to get started porting your native app to the mobile web. The live coded demo is here: http://emberjs.jsbin.com/lizep/7/edit?html,js,output

We build õ-age apps with Ember.js. We take teams from £ to • in no time flat.

programs to handle text streams, because that is a universal interface.”

Ember allows us to move complexity and state away from the server, and into
the browser.
APIs focus on domain logic, security and speed.

Convention over Configuration

Extend the Web Forward
•Soon: Ember will be module aware (no global app.) •soon: Ember will be written with es6 modules •Ember components <- Web components •primitive extensions match es6 (forEach etc.) •Where on THE DOM IS MY APP ATTACHED? •Ember promises (RSVP) are A+
Ember is built on concepts you already know.
MVC, BUT MORE LIKE than
Classes and mixins (ala RUBy)
properties have setters and getters (like Python)
If you get lost with Ember, finding a parallel concept may help.
Think about the problem before getting hung up on the API.
let’s write some code.
