Benefits of Using ReactJS

There are multiple large benefits of using ReactJS. Let's review them in-depth:
Component-Based Architecture

ReactJS uses a component-based approach for an average web app, allowing developers to build encapsulated components that manage their own state. This method leads to more manageable and reusable code. There is no need to rewrite a whole app when you engage in ReactJS development.

Virtual DOM

ReactJS implements a virtual DOM, which optimizes rendering and improves the performance of web applications. This results in a smoother and faster user experience, especially in complex web and mobile applications. ReactJS development services are, thus, more cost-efficient than others because they need less time for improvement.

Strong Community Support

Being an open-source library, ReactJS has a large and active community. This ensures continuous improvements for React software and app development services, a wealth of shared knowledge, and a vast array of third-party tools and extensions. Few libraries cover entire development processes as well as ReactJS. Ultimately, ReactJS app development becomes much simpler due to this long-term support.

Declarative UI

ReactJS’s declarative nature makes the code more predictable and easier to debug during, for example, web application development. Developers can design views for each state in the applications using React, and the platform will efficiently update and render the right components when data changes.

SEO Friendly

ReactJS can run on the server, rendering and returning the virtual DOM to the browser as a regular webpage. This capability of ReactJS solutions is crucial for SEO, as it ensures that search engines can index the content of custom web applications and web pages. Ultimately, ReactJS web development is among the most reliable approaches for a long-lasting software development process.

Strong Backing by Facebook

ReactJS is a popular framework that is maintained by Facebook. In this light, an average ReactJS app has the assurance of stability and ongoing investment in its development from a large corporation. This backing has contributed to ReactJS’s widespread adoption and enduring popularity in the web development community. When you invest in a ReactJS development company, you can be sure that its code will last for a long time.

What is React JS?

React is an open-source front-end JS library for creating user interfaces based on UI components. It’s supported by Facebook and its community. Using React with frameworks like Next.js, you can create single-page, mobile, or server-rendered apps. React doesn’t provide a complete “app library” and requires other additional libraries for a full-fledged app. Since the framework is designed and used especially for creating user interfaces, it doesn’t have all tools needed for the developers in the app development process.  

Why choose React JS?

Our React developers define four core benefits of using React app development:


Reusable components

React.js offers developers the opportunity to reuse code components. It reduces the development time and saves you money that can be spent on product promotion and branding.



Choosing a React.js development company is a winning strategy. Being efficient, React.js allows for better performance. React.js solutions load fast and aren’t resource-demanding.


Quick launch

React.js takes a few minutes for setting up and then it’s ready to use. You’ll quickly move to launch your development project. With React.js, you can also build PWA, one of the major trends in software development.


Highly adaptable

No matter how futuristic your project is. React.js helps implement both common and novel ideas. The only task is to select a reliable React.js partner. Our list of React.js interview questions may help you choose the best one.

How much does it cost to develop a ReactJS web application?

Before answering the question, we need to address much more information since the cost depends on various factors. To evaluate the approximate price of the React app, we have to define the features required for the app, the development time, the timeframe for completion, and the team involved in development. Also, it’s important to negotiate on code quality, scalability, and maintainability of the app and decide if you need junior or senior devs for the project. These questions are only several ones to set the price apart from other critical issues like maintenance costs, bug fixing, hosting, etc.

What are the skill-sets of your ReactJS developer?

Our developers are responsible and those who can easily fit into the time frame. They’re highly qualified experts who help each client find and implement the best web solution.


By the way, we present you with a great offer. You can hire a team of our best senior developers called Strike Force for a perfect start to your project. Within a month, they’ll set up the development environment, major development processes, and project architecture. Afterward, we suggest switching most of the team members to junior or mid-level developers, while senior developers stay as consultants. This way, you have a more affordable project with a perfect quality set from the start.


In KeenEthics, every expert in their tech domain does everything to get more satisfied users with UX audit. This approach is the best way to cut the development expenses and improve your ROI in the long run. At the same time, we eliminate the pain points of your users as well as improper design practices. Learn more in this UX presentation.


Finally, KeenEthics is a place for a motivated team with our mental health program. When working with KeenEthics, you hire a keen React.js development team of dedicated developers. Our Mental Health Officer monitors closely the mental state of each employee to ensure happiness, motivation, and loyalty. With our employee satisfaction checkups, we ensure low employee turnover and no associated project delays. Learn more in this mental health article.

How much time will it take to develop a ReactJS Project?

Usually, developing a React.js project can take around 8-10 days or up to weeks. As for creating apps, if you are a decent React web developer, you can build a simple app in less than a day. However, a complex production app or project can take even several months. There is no standard time. Here, the time duration depends on your requirements and ideas. Also, there are critical factors influencing the time needed for devising the project, like what a simple or complex project means for you, your level of competence with technology, and the size of the project team.

ReactJS and React Native: what is the difference?

React JS is a front-end library developed and maintained by Facebook. Today, it’s considered to be one of the widespread JS libraries with a good foundation and community. In development, React is used to handle the view layer for applications. You can create reusable UI components.


By choosing React Native, you can quickly develop mobile apps for different operating systems using the same codebase. RN is a mobile framework compiling to native app components and enabling you to device apps on various operating systems.


While React is a library for creating apps using JS, React Native is a whole platform, helping you build cross-platform apps and giving them a truly native feel.


If you need professional advice on these or other technologies, you can contact us, and we’ll gladly help you.
