6 Reasons why we love ReactJS

6 Reasons why we love ReactJS

ReactJS ( is a JavaScript library for building user interfaces which was open sourced by Facebook. At the time of its introduction, the underlying architecture appeared too crazy to work, but soon it captured the attention of the software development community with its unusual approach to DOM (Document Object Model) manipulations, Virtual DOM and building User Interfaces (UI).

We at TechSophy have been using React for building the UI of web and mobile applications for customers. It is our go-to library for implementing user interfaces. Here are some reasons why we love using ReactJS.

Build with Components Build with Components

Breaking down a user interface into smaller reusable components is very effective. One can think of the components as the building blocks for UI. We typically define a component with contained scope for styling, state management, and events. This essentially means that the development team can make CSS changes for a component confidently, without carrying any overhead for unused CSS code (you would appreciate this if you have maintained a global CSS file for the application). Additionally, Unit Testing is robust and predictable.

React makes no assumptions about your back-end. User interfaces can be built and deployed independent of the server-side stack. This means the development of UI can be decoupled with the server-side application and can be integrated reliably during deployment. React co-exists well with other JavaScript frameworks / libraries. This makes it easy to upscale the usage. One can try with a limited scope initially, without affecting the rest of the application.

Freedom to choose other tools that work with React Freedom to choose other tools that work with React

State management with ReactJS is usually good enough for simple pages. However, complex pages are not easy to maintain with the default state management contained within the component. There are multiple libraries which solve this problem differently and React allows the freedom to pick and choose the solution that works best for your application.

React works great with WebpackReact works great with Webpack

We at TechSophy love Webpack ( and use it for most of the frontend automation tasks. Here is a list of 5 functions that we automate using Webpack.

  1. Transpiling the new ES5 or 6 code into browser native JavaScript.
  2. Pre-process and optimize SASS, CSS, Images assets.
  3. Minification of JS and CSS assets.
  4. Automatically split the code for each entry point to different bundles.
  5. Live reloading, with Webpack dev server; this makes it very easy to test CSS / JS changes without manually rebuilding / deploying the code. This makes it fun and easy to work with React.

Native Mobile Apps with React Native Native Mobile Apps with React Native

React Native ( is a framework for building native apps for iOS and Android. It brings the Virtual DOM abstraction and design patterns available in ReactJS to mobile apps. This makes it easy for anyone with experience with React to make a transition to mobile app development. Using the tools, a ReactJS web developer is familiar with, we were able to build the native equivalent to Java, Objective-C.

Growing ecosystem Growing ecosystem

React releases are periodic, stable and are leading the innovation in JS frameworks / libraries. React, and the open source community continues to develop new libraries/plugins that make working with React even better. Facebook recently announced a complete rewrite of the React core algorithm (React Fiber and is rumored to be already in use on their social media site.
