This is a brain dump of my experience trying to get something going with Ember.js. My goal was to get to know the ins and outs of the framework by completing a pretty well defined task that I had lots of domain knowledge about. In this case reproducing a simple Yammer feed. As of this time, I have not been able to complete that task. So this is a subjective rundown of the things I think make it difficult to get a handle on Ember. NOTE: My comments are addressing the Ember team and giving suggestions on what they could do to improve the situation.

App setup

The new guides have pretty good explanation of the various parts of the framework; routers, models, templates, views. But it's not clear how they all get strapped together to make something that works. There are snippets of examples all over the place like:

App.Router.map(function() {
  match('/home').to('home');
});

// `f` is assumed to sporadically fail with `TemporaryNetworkError` instances.
// If one of those happens, we want to retry until it doesn't.
// If `f` fails with something else, then we should re-throw: we don't know how to handle that, and it's a
// sign something went wrong. Since `f` is a good promise-returning function, it only ever fulfills or rejects;
// it has no synchronous behavior (e.g. throwing).
function dontGiveUp(f) {
    return f().then(
        undefined, // pass through success

// And important point to remember is that and width

Things to do when IE9 Beta comes out

Note significant features added since IE9 PP4

• Implemented but not announced: box-shadow, hsla
• Expecting: 2d transforms, css animation, css transitions, flexible box model
• Maybe: gradients, columns, reflections, svg filters, uncrippling @font-face, 3d transforms
• Maybe version auto-update functionality

Test Modernizr against it

• Does it still throw an error checking elem.msTransform?
