Apart from the commonality that they are two popular JavaScript frameworks and a library respectively, Angular, Ember and React have a separate history of their own. A web application JavaScript framework that originated in 2009, AngularJS is great for building highly active and interactive web applications. Post its creation, React.js went open source in 2013. React.js is ideal for large web applications whose data is set to change frequently. Ember.js first made its appearance in 2007 as SproutCore. In late 2011, post a Facebook takeover, SproutCore was renamed Ember. It has turned out to be best suited for one-page web applications.

AngularJS

1. You can create customized Document Object Model (DOM) elements using Angular. Back end communication is taken care of, views and controllers play a critical part in making of the UI.

2. Two-way data bindings is another unique feature that makes UI design and alteration a comparatively easy process. Automatic data synchronization between view and model components is another two-way-binding enabled feature.

3. All common and related functionality are held together by the services side. The framework facilitates extension of HTML syntax, so that the application is compact and clean. The use of directives so that HTML dialect can be extended, is another notable feature.

4. Equally suited to desktop and mobile applications, Angularjs development facilitates easy testing. This also encourages comprehension and in the making of strong in-built services.

5. Dependency injection is a big plus feature, automatically loading new modules that you may require. For example, if you need a R data visualization along with additional elements, the dependency injection functionality will assign everything for you.

6. If you looking for packaging features, concerning running and deploying your code as you want to, Angular has its limitations. For example, if you want to maintain the loading time, while adding new features without affecting faster loading, all Angular has got is HTML templates.

7. When it comes to template-building, Angular is miles ahead of React, offering umpteen robust solutions. Angular can attribute its popularity to building quality UI of many web applications. It is way ahead of Ember and React with regards to this function.

8. Abstraction helps in faster development, even as unnecessary details are hidden. Angular’s abstraction needs attention and acute understanding the framework's internal workings may be a necessity, while code debugging. Angular is great for HTML code debugging.

9. Angular is great with code reuse, you could always get a hang of using Angular libraries. There is a whole lot of ready tools that Angular offers, making it the best of the trio when it comes to code reuse.

10. When you want to work around lot of code, Angular is your best bet. With concerns to data modeling, Angular's performance is limited to use of smaller data models. This helps in making the code more simple and quite easy to test. It also means that breaking down and rebuilding code will an additional part of the process. Finally, Angular ensures an all-round performance with lesser lines of code. Vevo, Youtube, Freelancer, istockphoto.com and weather.com are some popular websites running on Angular.

Ember.js

1. Ember is a single-page web application specialist, based as it is on the model-view-controller (MVC) pattern. Developers can use the best coding practices and methods to create single-page applications that are also scalable.

2. Ember also uses two-way bindings for registering HTML updates on a web page. Although primarily used a web application, mobile and desktop applications can also use Ember. A prominent example is the Apple Music desktop application.

3. Ember is similar to Angular in many respects, it has really worked well with large application ecosystems.

4. That Ember has a release cycle of 6 weeks adds to its advantage, this makes it an ideal choice for applications in need of iteration.

5. Ember has fixed notions on the way things work out, developers will find it easier to set up structures within its confines.

6. Has a strong data layer that integrates well with languages like Ruby on Rails.

7. Even if you don't define several aspects yourself, Ember works on self-configuration of the same.

8. Ember requires less typing too, though there is certain completeness and polish to React's explicitness and Angular's all-round abilities.

9. Just like React, Ember has an issue with scaling too. But in most cases, Key-Value Observing (KVO) and global store model objects ensure that the problem is solved.

10. Yahoo!, Linkedin, Microsoft, TinderBox and Netflix are among the websites that use Ember.

React.js

1. A virtual DOM showcases the changes in React, as compared to a real DOM in Angular. Updates occur faster in this framework because in the real DOM, the only change will be the update. DOM access is still a slow functioning part of a web application, React thus performs better when the DOM is optimized.

2. If you want to test how good or bad a coder you are, go for data model structuring in React. You have an all-round flexibility when it comes to working on the same in React, which could be both good and bad, or you would rather stick to Angular.

3. In total contrast to Angular, React is against two-way binding. They deliberately stay away from it and make use of explicit updates instead.

4. Data flow is uni-directional. It thus takes more code to make things work in React, otherwise easily done in data binding.

5. React is as flexible as they go when it comes to code re-use, you can shape it as per your requirements.

6. When it comes to packaging, React is much more flexible than Angular. With its plain JavaScript background, it allows us to push in various solutions like requirejs and webpack.

7. React has limitations to its abstraction. But this is solved to a large extent, by using mixins - those with a certain execution sequence going for it.

8. Code changes effects are limited or very local here. React is great for JavaScript debugging, as it's structure is limited and concentrated, you always know where to look for bugs.

9. React can be considered the lightest of the three, it is filled with the least conditions and eliminates the need to use extra elements like plugins. Although React is scalable, its uni-directional flow causes the main components taking up the load.

10. JSX, another React element, with its XML-type syntax is aimed at making it more easy for designers to understand, especially anyone working with HTML. Facebook, Flipkart, Instagram, The New York Times and Flipboard are among the prominent websites using React.
