5 React.js Advantages for Your Business’ App

About the React Library

React.js is used for handling the view layer of web and mobile applications. Since it processes only user interfaces (UI), React isn’t actually a complete MVC framework like AngularJS, for example. In the Model–view–controller architecture, it can only be employed in combination with other JavaScript frameworks or libraries.

React.js Advantages

React facilitates the creation of interactive, stateful and reusable UI components and the development of web applications which can change data without reloading the page. Here are top-5 React.js advantages for a business over other technologies.

1. Simplicity

The use of React.js components provides a great advantage in the development. Starting with small things, the developers use them to build bigger things, and then those to build web apps. Each component has its own logic, controls its own rendering, and can be reused wherever needed. The ability to expand small components and create customizable ones offers greater flexibility necessary for a project.

2. Performance

Apps with a lot of user interaction and data updates normally require a careful consideration of how the app structure is going to impact performance. The Document Object Model is very slow to change and update. A server constantly checks the difference caused by the changes to give the necessary response. To respond properly, it needs to update the DOM trees of the whole document, which is not ergonomically valid: nowadays DOM trees contain thousands of elements. This problem is solved by using the virtual DOM.

3. One-Way Data Binding

UI libraries watch for changes to the data model and update the corresponding part of the DOM when these changes occur, or watch for changes in the DOM and update the data model accordingly. This process, called two-way data binding, can make the work with UIs very complex and confusing.

4. Community

As an open-source library with over 1,000 contributors, React.js is constantly developing. Many things are already available, while the rest of the codebase can be reused. Major changes to the framework go through the Future of React repo, Issues and PR. This enables the community to provide feedback on new potential features, experimental APIs, and JS syntax improvements.

5. Native Approach

React Native is one of the fastest and most efficient environments for the creation of mobile applications. Its working principles are basically the same as React.js except that it’s not manipulating the Document Object Model via the virtual DOM but some native views. It runs in a background process which interprets JavaScript on the device and communicates with the native platform via a serializable, asynchronous and batched Bridge. React Native doesn’t rely on HTML5 at all; everything is written in JavaScript and relies on native SDKs.

  • Instagram.com. The library helped optimize the web app and make it fast and comfortable for users to access the social platform. Now, both the mobile and web apps are built with React.
  • Netflix. Netflix chose React.js due to its one-way data binding and declarative approach to programming.
  • Pinterest. The app switched from an internal UI library to React because of its virtual Document Object Model.
  • Two-way data binding may cause cascading failures in React. To prevent two-way binding while integrating an MVC, Flux or Redux should be utilized.
  • The virtual DOM makes React more CPU-intensive than other methods of updating the DOM. For instance, jQuery and pure JavaScript will be about 3 times faster than React to load and display the simplest ‘Hello, world’ application in Chrome. However, improvements can be realized with memorization and other good development practices.
  • Too many different ways to create and manage a React component, as well as state management tools emerging, make it difficult to select the best option. However, it’s not an issue once the project team has adopted a certain workflow and developed own documentation for the easier introduction to new team members and/or the project hand-over.

Conclusion

Aiming primarily to provide speed, simplicity, and scalability, React.js helps build and support highly dynamic web and mobile applications. The virtual DOM alone justifies the use of React over other UI libraries. It facilitates the developers’ work and the users’ interaction with the product. Reusable and highly testable React.js components further increase development speed and quality. Combining the speed of JavaScript with simplicity and improved performance, the library can significantly optimize efforts of web development, saving the employers’ time and money, and offer smart solutions to businesses.
