It supports the MVC (Model–view–controller),MVVM (Modal-view-ViewModal) and MVW (Modal-View-Whatever) design paradigm which supports standard two-way data binding. In MVW, whatever stands for “whatever works for you”. Angular gives you the lot of flexibility to separate presentation logic from business logic and presentation state. In MVC, your data is updated on both the UI (presentation state) and back-end (coding or server side) whenever it detects some changes in the engine.
As the UI components (View) are separated from the Model components, you can easily build reusable components for amazing and user-interfaces!
Recently Angular 2.0 has been released in OCT 2016, which claims to improve the speed & performance of mobile and desktop and take it further via web workers and server-side rendering. Meet huge data requirements by building data models on RxJS, Immutable.js or another push-model. Angular Loved by Millions of developers across the globe and it’s highly recommended for anyone who wants a powerful MVC framework with a strong and modern infrastructure that takes care of everything for you to build single page applications.
Angular is also planning to release Angular 4.0 then it called ‘Angular’

As your app comes into existence and develops, it’s advantageous to ensure that your components are used in right manner and React app consists of Reusable components, which makes code reuse, testing, and separation of concerns easy.
ReactJS is not only “V” in MVC, it has stateful components, it handles mapping from input to state changes, and it renders components. I would highly recommend this Framework if you just need a front-end development Framework to build an incredibly complex and awesome UI through the power View Layers. In this sense, it does everything that an MVC does.
Apart from Facebook and Instagram, there are several companies that use React, including Whatsapp, BBC, PayPal, Netflix, Dropbox, etc.
Ember.js is based on Model–view–viewmodel (MVVM) design pattern, which is slightly different than MVC, In the sense that the view model is more than view and handles most if not all of the view’s display logic
For the fast server-side rendering with nodejs and adding the animation in UI. we need to use Ember CLI addon Fastboot.js and liquid-fire.js, so the applications have extremely enhanced performance of complex UI with animation.
Ember supports Handlebars integrated templates that update the data changes automatically. It also provides routes, dependency injection, declarative two-way data binding and Custom components.
Knockout has no dependencies on any other libraries and it supports all mainstream browsers like IE 6+, Firefox 3.5+, Chrome, Opera, Safari (desktop/mobile) it’s not popular as much competitors like Angular, Ember or Backbone. The slow growth is simply because of improvements and adding more features in framework.

Ever since its release, the MeteorJS community too is vibrant and helpful. You would find tons of resources, tutorials and custom packages that give super powers to solve your development errors and develop your app in MeteorJS.
From Performance perspective, any changes in the database are reflected back on the UI in the real time and vice versa without the handshake between different languages with minimal development efforts.

The most important feature in this framework is that you can use selective modules with it for your specific needs. For example, you need to write HTML code, fetch the JSON and create a Vue instance to create the small effects that can reused!
This framework can be easily integrated to any third-party template engine, however, by default it has dependancy on Underscore templates along with JQuery, It has the RESTful JSON interface with the support of MVC (Model–view–controller) design pattern.
If you ever heard or used the famous social news networking service reddit, then you will be interested to hear that it uses the Backbone.js for several of its single-page applications. Jeremy Ashkenas who developed the Backbone.js, it has also created the Underscore templates as well as CoffeScript, so you are assured that the developer knows his stuff.
This framework provides models with key-value, views and several modules within a single bundle, so you don’t need to download the other external packages, saving you time. The source-code is available on Github, which means you can further modify it for your needs. There are several big companies who’s using backbone.js 500px Web, Airbnb, Pinterest, Reddit, WordPress.com, USA Today.com,LinkedIn Mobile.
