AngularJS has a J2EE mindset. Where libraries grow to become as hard to learn as programming languages themselves. It does not make semantic sense to me anymore. Here is an example from the site: Length (float): {{length}} This is not a valid float number! How semantic is ng-show="form.length.$error.float? smart-float sounds like C++.

I only looked superficially at React, so maybe I got something wrong, but the HTML/XML intermingled with Javascript seems extremely off-putting to me, akin to ASP/JSP/PHP.

That puts me off too, it's too PHP, as you said, but I love React because I use it with Coffeescript, which eliminates the need for a JSX compilator: http://blog.vjeux.com/2013/javascript/react-coffeescript.htm...

(You can do the same thing with pure JS, there are some forms of simplifying the React.DOM.div() calls, but coffeescript makes it beautiful.)

The new DI looks confusing. The old way is super simple to understand. You inject the location provider and call it. In the new way however I don't understand what's going on at all. Where can I find a simple example?

https://github.com/angular/di.js/blob/master/example/kitchen... Seems pretty simple, imo.

I don't understand how that correlates to the current DI.

How do I rewrite the following using the new DI system?

  function MyCtrl($http, Base64) {
  	$http.get('http://www.example.com').success(function (data) {
  		console.log(Base64.decode(data));
  	});
  }

I'm curious what happens when you want to share models across components. In angular.js you would use services to do this, but what's the analog in React?

I have been successful by instantiating separate services to perform REST operations and a global event emitter to establish communication between all the services and all the components that relate to these services in any way.

I cringe when I hear the words "global" and "event" together in the same sentence. Projects I've worked on in the past that relied heavily on global events often became a maintainability nightmare.

Angular is starting to remind me more and more of JSF + CDI which immediately triggers a negative visceral reaction for me. But, if I step back and think for a moment, most of what I despised about working with JSF was related to the amount of state it needs to maintain between the browser and server. If that state is completely contained on the client and the client maintains a stateless connection to the server, it may actually work out well.

Why? Please share your experiences. I don't understand what's the utility of event emitters if not for serving as glue to all the separate components of an app. Am I wrong?

> Dependency Injection is still a key differentiator between Angular and other client side frameworks

Why not just take Require.JS and use it as a dependency injector, like any other client-side frameworks allow you to do?

IMO Angular is trying too hard to be everything, while it is now de facto a template system with an excellent support of custom directives and two-way data-binding.

For example, Angular could be a good choice for a View layer of an app built on top of Backbone, since it moves away from opinionating the View layer. But it's just too much fuss happening around this templating system in Angular.

An yet another simple text blog that is 100%, completely, utterly broken an useless without JavaScript enable. There isn't even any compelling feature. Besides the sliding out mention there is _no_ reason JavaScript even needs to be on this page.

I don't get why BlogSpot an so many other sites require javascript to o absolutely nothing of value just to see the site. It's maddening and appalling.

Agree 100% with your post - some of these complaints are misrepresenting the aspects that are not as desired in Angular. I've used Angular quite extensively for the past 1 1/2 years, and most of the complaints I have with it are more nuanced, such as having to dynamically inject some custom directives via $compile in a service method provided to a controller due to the complexity of being able to alter the attributes…

I agree with you that since your elements appear to not be a part of the HTML5 spec they must be custom and are directives, wouldn't it be a good idea to mark them as such in some way? Maybe prepend them with "an-" or something? The reason being, considering that HTML5 is an ever evolving spec that it might be possible for a new element to be introduced that could be using the same name as one of your examples. That…

Actually, it's a little more complicated than this even. Not only might HTML add more tags, but a non-standard tag might be a W3C custom element: http://www.w3.org/TR/custom-elements/

When users gain the ability to define their own tags, you might not know which ones are driven by directives, the custom element, or both even.

This is true. AngularJS is much better than what we had before, it is kind of large and monolithic. The cycle probably goes thusly: Large monolithic framework comes and shows everyone a new way of doing things (Angular/Django). People think it is too large and monolithic, so make microframeworks (Flask/Whatever comes after Angular). The next step will be a kind of happy medium.

I never understood how JQuery and JS were just dumped the past 3-4 years in favor of all thse complex frameworks like AngularJS, Ember, etc... is there something these frameworks can do that JQuery can't? Can they make fancy single page apps and JQuery can't? I need to be enlightened.

Or is it simply ppl need to exercise their mental creativity?
