AngularJS make it easier for developers to write clean and maintainable code by allowing them to use HTML as a template language. It allows programmers to use HTML just like XML, and add functionality to the application by extending HTML elements. Also, the framework enables developers to add functionality to the front-end and back-end of the application with less code. As Angular is a model-view-controller (MVC) framework, the developers can build and maintain the web application easily by keeping the business logic and user interface separate. Also, they can take advantage of the two-way data binding feature of Angular to implement AJAX functionality simply by creating custom HTML tags.
React comes with features to simplify development of user interfaces. It further makes traditional data binding more effective by implementing one-way reflective data binding. Many developers even use React along with other MVC framework to create the view or user interface of the application more robust. React further boosts the performance of the application by replacing its DOM with a simpler programming model. Also, the framework allows developers to render server-side code with Node.js.
As a MVC framework, Ember comes with features to simplify development of front-end user interfaces. Like AngularJS, Ember also supports two way data binding. Hence, it becomes easier for developers to keep the view updated when changes are made to the model and keep the model updated when the view changes. At the same time, Ember allows programmers to boost the performance of the website by rendering DOM on sever side. The developers can take advantage of the Fastboot.js module included in Ember to render DOM on sever side without putting extra effort.
