Why go with REACT.JS

Posted by Amit on May 24, 2018


From past few years there has been constant need to improve user-experience and it is keeping developers on their toes and making them adapt to new technologies and trends that will deliver better results. One such technology that is attracting everyone’s attention due to its impressive features is the React JS. Facebook made react.JS opensource and now its being used by lots of popular apps such as WhatsApp, Netflix, and Instagram etc.


As we know React (also known as React.js or ReactJS) is an open-source JavaScript library for rendering views. While full frameworks like AngularJS provide the model, view, and controller, REACT is a library that caters only to the view. It uses one-way data binding, but with a unique twist that helps it gain a huge performance advantage over competing technologies.

Key features which drive the use of REACT are:

  1. Simplicity:
    ReactJS is just simpler to grasp right away. The component-based approach, well-defined lifecycle, and use of just plain JavaScript make React very simple to learn, build a professional web (and mobile applications), and support it.
  2. Native Approach:
    Normally when you try to build an app for mobile devices using JavaScript, you have to rely on a cross-platform framework like Cordova or Ionic. While these frameworks can greatly speed up development time, they’ll never be as sleek and smooth as a native app. Enter React Native, a framework that enables you to build components for native UI widgets the same way you build them for HTML. React treats the view layer as a pure output of state, so switching its purpose from the web to mobile is as simple as swapping your tags for tags via the React Native framework
  3. Virtual DOM:
    This is the key piece of tech responsible for the magic behind React’s amazing rendering performance. Instead of manipulating the DOM directly (which can be error prone), React stores two copies of a Virtual DOM, the original and an updated version that reflects changes fed in from the view. The two versions are run through a React function that singles out the differences and outputs a stream of DOM operations that only alter the parts of the view that changed. As a result, time and resources are saved, as only the parts that are changing are affected by modifications in the view.
  4. JSX Files:
    JSX files go against the modern tendency to want to keep HTML and JavaScript code separate. This isn’t a bad thing with REACT’S sleek and simple syntax, however—you end up with a single self-contained component that tells you exactly how it will render in the view. It also helps that it’s optional, so those who are more accustomed to traditional programming paradigms don’t have to use it if they don’t want to
  5. Data Binding:
    React uses one-way data binding and an application architecture called Flux controls the flow of data to components through one control point – the dispatcher. It's easier to debug self-contained components of large ReactJS ap
  6. Performance:
    React does not offer any concept of a built-in container for dependency. You can use Browserify, Require JS, EcmaScript 6 modules which we can use via Babel, ReactJS-di to inject dependencies automatically
  7. Testability:
    ReactJS applications are super easy to test. React views can be treated as functions of the state, so we can manipulate with state we pass to the ReactJS view and look at the output and triggered actions, events, functions, etc.

When should we suggest React?

When lots of dynamic content is changing within the view, then React is the technology to be used. Most client-side solutions on the web today struggle with rendering large lists of items within a single view. This "struggle" may be on the order of milliseconds, but in this increasingly digital world, a half a second delay is all it takes to kill your user experience. It’s why sites that have a lot of dynamic, constantly changing, data-intensive content like Instagram or Facebook choose to power their applications with React.

As a library, you can also use React as the view component of AngularJS or other frameworks, because it does not tie you to a specific technology stack. That said, there’s a quickly growing community and a few existing libraries and add-ons that can help you build an app from scratch. Consider Flux, the application architecture Facebook uses to create an application powered by React. React is also perfect for those familiar with ClojureScript and its immutable data structures—the Om project is the rising star for those looking to build dynamic applications using these technologies.
