How to Cast a Javascript Framework for your Project

If you have been into web development from the past few years, you must have understood that Javascript frameworks are proving themselves as an engaging way to build an adaptive, interactive and rational web application. Although there are a lot many choices for the developers, they should be aware of the knack of the each one. For the rapid development of web applications, it is important to acknowledge various factors like performance, sustainability and adaptability of a particular Js script. Despite being plentiful in number, four of the JavaScripts stand out: Angular, Ember, Backbone and React. Let us see which has the most to offer:

Angular.js
Angular.js is an open source client side MVC framework supporting the rapid development of client-side web applications. It gives HTML super power by adding all crucial features necessary to build dynamic user interface. Extending HTML with AngularJS is very simple, one can use standard AngularJS directive or develop a custom directive and mount it on any device.
The best part of this framework is that it works on the concept of two way data binding. It is the framework that revolutionized the concept of model view controller architecture in web applications.
In this framework view and model synchronizes when the user interacts with interface and provides input, the logic in the model is executed and the DOM gets updated. The reverse is true as well, if the model gets updated, the view is re-rendered. This essentially takes away all the pain of writing manual code for DOM manipulation.

USPs
Features like Two way data binding, Directives and Dependency injection are much loved features as it allows a reduction in the amount of code required to create dynamic views, gives freedom to extend HTML by attaching special behaviors to parts of the DOM and allows developers to easily include services in their modules and inject mock data into the component.
Apart from this, Angular treasures Google as a sponsor.

Bottom-line
Angular’s usability width unlike Backbone lies between small projects to enterprise applications and hence it remains unparalleled with improvements and advancements it brings with every new release.

Ember.js
Ember.js is another dynamic MVC JavaScript framework. It gives the best competition to Angular and React when it comes to building an interactive frontend UI.
Ember too works on the concept of two way data binding, i.e. updates view when the model changes and update model when the view changes, keeping both in sync all of the time.
It is strengthening itself with the new superpower of Fastboot.js module that allows server side rendering of DOM for better performance in complex UI rendering.

USPs
Ember’s principle of “convention over configuration” helps developers to skip a routine and humdrum task of reinventing the wheel. This helps developers to focus on the unique problems of their project.
Since Ember.js covers the best features of both AngularJS and ReactJS, it is appropriate to expect exceptional growth of Ember.js in the race of JS frameworks.

Bottom-line
It is highly opinionated, so if you like to roll your own, it may not be for you, still it can be used for medium to large projects with notable improvisations like having a plan to start the support for server- side rendering. Overall, it is a good framework.

Backbone.js
Backbone.js gives frame to web applications by presenting models, collections and views with custom events and a rich API and connects it to your existing API over a RESTful JSON interface.
Backbone.js is an attempt to discover minimal set of data- structuring (models and collections) and user interface (views and URLs) primitives that are generally useful when building web applications with JavaScript.
Its USP is its flexibility as user can make anything on the top of it by adding his own code or can use third party JavaScript frameworks.

USPs
Because it’s so lightweight, Backbone shines brightest when used in simpler projects where speed is a priority – think single page apps (Twitter, Pinterest) or a widget that is part of a traditional web application.

Bottom-line
Backbone is the framework that suits the best in the hands of experienced developers building single page applications (SPAs) and widgets. But of course, if one wants to extend the limits , he should thoroughly know the options for server-side rendering additional libraries and plugins he may need in order to build the application.

React.js
React.js proves to be the best when it comes to building the large scale applications of extreme dynamic nature. eg. Facebook and Instagram interface.
It is best at rendering complex user interfaces with high performance. The basic fundamental behind React is the concept of virtual DOM. ReactJS utilizes a virtual DOM, which can be rendered either at client side or server side and communicate back and forth.
Its re usability is brought out in the form of reactive components. React component libraries can be created and used across applications or made available for public use.

USPs
React is very fast and easy to learn framework. It significantly has less of ‘domain specific language’, making it easy to handle JS framework for the developers having the knack of JavaScript. It has a component- based approach, allowing maximum code reuse through mixing and matching of the components.
Another very cool benefit of React is that you can use it to create mobile applications. React Native allows developers to learn React once, and use it to write both web and iOS apps (Android is coming soon).
React also supports server-side rendering which helps search engines to index the site while also provide faster page loads.

Bottom-line
React is a framework which has project width of zero to infinity. Any size project can confidently use React, as it encompasses all the features which developers look while choosing a framework. Facebook and Instagram UI are the best things to refer to understand its potential or usability.

Conclusion
Due to increasing demand of interactive web applications JS frameworks have become the indispensable choice of developers. Various frameworks offer different choices and methods to render the complex user interface and make single web page application more useful and faster. Conclusively, the framework you choose will be a subjective choice depending on the project your team has to work on. However, for a developer – particularly a front-end developer , it is best to take the plunge and gain expertise with one of them.
