What is React JS Web Development?
React JS Web Development can be used as a base in the development of single-page or mobile applications. However, React is only concerned with rendering data to the DOM, and so creating React applications usually requires the use of additional libraries for state management and routing.
Redux and React Router are respective examples of such libraries.
React JS Web Development Features:
Components − React is all about components. You need to think of everything as a component. This will help you maintain the code when working on larger scale projects.
Unidirectional data flow and Flux − React implements one-way data flow which makes it easy to reason about your app. Flux is a pattern that helps keeping your data unidirectional.
License − React is licensed under the Facebook Inc. Documentation is licensed under CC BY 4.0.
Can be used on client and server side as well as with other frameworks.
Component and data patterns improve readability, which helps to maintain larger apps.
Covers only the view layer of the app, hence you still need to choose other technologies to get a complete tooling set for development.
Uses inline templating and JSX, which might seem awkward to some developers.

React creates a virtual DOM. When state changes in a component it firstly runs a “diffing” algorithm, which identifies what has changed in the virtual DOM. The second step is reconciliation, where it updates the DOM with the results of diff.
