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

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.
