React Overview-

React is an open source library, maintained and used by Facebook.  It is also used by many fortune 500 companies.

React is a library not a framework like Angular/Ember and React has many advantages compared to other libraries or frameworks. Why you should use it, below is the quick React Overview.

React Overview


Learn once, write everywhere –

React was created for client-side component only in 2013 but it is robust and feature-rich library now and it has a strong ecosystem. You can create Static Sites (using Phenomic), a true Native Mobile app (using React Native), Desktop apps (using Electron), Virtual Reality website (using React VR).

Easy to Learn 

React is a very small library and it has few simple APIs so it is very easy to learn. React is based on three design concept – Components, Reactive updates and Virtual view in memory and uses the pure JavaScript approach.


React library size is very small and it uses virtual DOM to updates the required section of UI. This approach makes UI rendering very fast and application consumes less CPU and battery of the device.

Community support 

React has strong community support and it is one of the most popular projects on GitHub. If you will try to do something using React, you will find an online example of it.

Component design

You can create reusable components using React and it is very useful to implement the ‘Client-side UI composition pattern’ in the MicroServices world. Each MicroServices team can develop a client-side UI component using React, and UI team will be responsible to implement the page skeletons that build pages/screens by composing multiple, service-specific UI components.

No two-way data-binding risk –

There is a risk with two way data-binding if an application is not designed carefully. With two way data-binding, UI change will update model, this model can update another model and another model will update associated UI. This will lead to an unpredictable result, cascade update and debugging will be tricky. React is based on one-way data-binding and application is easy to maintain and perform better, other library like Angular has shifted gear to support this binding approach.


React enhance the javascript and add HTML code in the javascript code instead of enhancing HTML code like Angular (template-centric). React uses the power of javascript and developer can use javascript syntax instead of framework-specific syntax.


React is a library so it can be integrated with any other JavaScript framework easily like Angular to implement the few components of the UI.


You do not need to migrate the complete application/UI at the same time. You can divide the UI based on component pattern and do the migration in phases to reduce the risk.


Last but not the least, React is based on MIT License now.

This React Overview blog has almost all high level React features and it would help you to compare React with other JavaScript frameworks.
