7 React JS Advantages You Should Know About When You Build a Digital Product

React JS Advantages to know for web and mobile development

It seems that React, the JavaScript library that was initially released in 2013, is taking over the world of front-end development.

Over 61,000 developers state that they use the library for their projects. Practically 9,000 world-known brands including Uber, Airbnb, Facebook, Pinterest, Netflix, Udemy, and Snapchat report that they have opted for React at some stage of the development phase.

In this article, let’s dot the i’s and cross the t’s of the primary React.js benefits you should pay attention to when considering React as a tech stack for your project. Additionally, we’ll touch on choosing between React and Angular, and the type of projects that each technology fits the best.

Why Build a Project on React?

Based on the experience of the Agente team building projects with the help of this JavaScript library, we’ve selected seven top business benefits of React JS that make this tech stack a real difference.

High Performance

It takes 0.05 seconds (!) for a user to form an opinion about your site before navigating away, says SWEOR, the step-by-step marketing platform. With the world going online, it’s of primary importance to catch the user’s attention by whatever means necessary and retain your target audience.

Site performance, load time, and usability stand in the frontline of the battle for the users’ attention. And React was undoubtedly built with performance in mind.

React compares favorably with the other JS technologies because it doesn’t try to maintain the HTML document directly (also known as DOM). In other words, other technologies require an update of multiple elements, while the user interacts with the web application, which leads to lower response times.


React uses a virtual representation of DOM, which allows the library to speed up its performance drastically. This is achieved by running operations against the virtual DOM when the user interacts with an application. Only then are the composite set of changes displayed at the front end.

Fast Development

If you’ve ever wanted to launch your project as soon as possible, then you understand how hard it may be to find a tech stack that combines both high quality and low development time.

It won’t come as a major surprise, but that’s what React development offers: efficiency.

Efficiency is achieved through the modular nature of the library. React allows you to break your project into separate components and re-utilize the required individual parts on both the client and server sides. In other words, each developer can work on writing separate parts of your app without influencing the logic of the whole project when it becomes necessary to make changes.

react js popularity growth

Let’s refer to the Google Webmaster Blog:

Faster sites create happy users and we've seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don't just improve user experience; recent data shows that improving site speed also reduces operating costs.

Well-performing websites have fewer abandonments. SEO increases the average session duration and other parameters that are so critical to ranking higher in the Google results pages.

The backend rendering of React enables a reduced the load time, thus making web apps better optimized for search engines.

It’s one of the main benefits of using React.js if you are thinking about the long-term prosperity of your online product.

Rich UI 

One of the components to the success of an app is the quality of its user interface. A poorly designed UI makes a project less attractive for the end user.

The declarative components of React make it ideal for UI development, as well as either simple or complex—yet highly functional—UIs.

For example, React DnD allows the building of drag-and-drop events, thus making user interfaces more engaging and interactive. Its style components allow the use of CSS and the adjustment of complex design requirements to a specific business’s needs in less time.

Stable React Code

Ensured by the downward dataflow, React guarantees that no parent data is affected if there are changes in its child structure.

What does this mean?

If changes are made in a specific object, developers can only modify its states and make specific amendments. As a result, updates will affect a specific component only.

And the good news?

Your application will be more stable and run more smoothly.

Good for Mobile

One of the tangible benefits of React is the possibility of seamlessly switching to React Native, the framework used to develop mobile solutions. The list of renowned companies that have opted for this technology speak for themselves. Facebook, Instagram, Pinterest, and Salesforce are just some of the famous apps or companies with mobile apps using React Native.

Why do brands make such a choice?

It’s one of the most reliable and robust mobile development technologies. Like a majestic unicorn with great capabilities, the framework allows for the development of cross-platform applications that run on iOS and Android equally well.

Community of Developers

Following—one of the strongest React.js benefits. Did you know that React first started at Facebook? The social media giant continues to support and maintain the JS library, together with a multitude of independent contributors across the globe.

Why is it important for your project?

Such support from the community of developers and contributors helps to ensure that React is reliable, stable, bug-free and up-to-date. Additionally, by sharing their knowledge online, React developers help each other to deal with specific issues faster using tried and tested means.

React vs. Angular. What to Choose?

Both React and Angular are powerful. Both of them are frequently chosen for the development of single- and multi-page applications.

But as similar as they seem to be, they are like comparing Messi to Ronaldo. Both React and Angular are powerful and well-supported, and their choice should be based solely on: 

  1. the type of an app you want to build, 
  2. app complexity, 
  3. application size, 
  4. the float time you have on development.

As it will be hard to depict any significant performance differences between the technologies, let’s highlight the type of projects that suit each one the best?

See the examples of projects built on Angular.


React is a JavaScript framework that was developed by Facebook; it is still gets maintained by the social media giant.

React is perfect for projects that must be developed yesterday. In other words, if fast implementation, prototyping or creation of the proof of concept is what you currently need, then React is ideally suited to the job.

As React is just a framework that provides the “view” in the “model-view-controller” architecture, the technology brings more freedom if compared to Angular. However, to create applications that are more complex and advanced, your React developers will need to choose other extra libraries, and it might take some time to make them all function together—or it might be difficult just at the beginning.

From a business perspective, React is considered to be the right choice when developing open web services, such as:

  • Marketplaces
  • eCommerce sites or platforms
  • Startups that require scalability
  • Small separate widgets for a site
  • Calculators
  • Social cards
  • Weather apps
  • Messaging apps
  • Productivity apps
  • Entertainment apps, and more.


Angular is the JavaScript framework, written in TypeScript, developed and maintained by Google.

Angular is known to be perfect for comprehensive solutions that need to be updated regularly, function fully and be compatible with one another.

The framework is divided into modules, each responsible for an app layer. It allows users to choose and download only those modules that are required. It helps take the size of an app in full control, as well as add new functionalities seamlessly as the project scales up. 

Thus, the well-defined architecture of Angular makes it better structured, and thus more suited to long-term projects, as well as rotating development teams.

Briefly, the following projects would be a great fit for Angular:

  • CRM systems
  • CMS
  • Management systems
  • Complex apps
  • Social media projects
  • Startups that require scalability
  • News portals
  • Rich web apps
