What Is ReactJS and How Does It Work?
ReactJS, or simply React, is an open-source JavaScript library, developed and maintained by Meta, designed specifically for building user interfaces. What sets it apart from other web development tools is its components use.
Imagine building a website the way you’d assemble a LEGO set — each piece (or component) can be developed, tested, and reused independently. This modular approach makes ReactJS a favorite for developers working on large-scale applications.
But here’s the real kicker: ReactJS doesn’t update the entire webpage when something changes. Instead, it uses a virtual document object model (DOM), which is essentially a lightweight copy of the real DOM. React compares this virtual version with the actual one, figures out what changed, and updates only the specific elements.
This technique is what keeps React apps blazing fast, even when they’re doing a lot behind the scenes.
8 Benefits of ReactJS
ReactJS isn’t just another JavaScript library — it’s the secret weapon that developers use to build fast, scalable, and user-friendly applications. Of the one million websites with the highest traffic, 155,670 are React users.
Let’s explore why.
- Rich user interfaces
- Supporting large-scale apps
- SEO-friendly
- Performance optimization
- Cross-platform compatibility with React Native
- Reducing technical debt
- Backward compatibility
- Longevity and future-proofing
Rich User Interfaces
While web design vs. web development often sparks debates, ReactJS seamlessly blends design and development by enabling rich user interfaces. Because the library allows developers to control the state of components efficiently, they can easily build dynamic UIs that look and feel great, without dealing with the sluggishness that can plague traditional web apps.
By leveraging established UI patterns, developers can create intuitive and interactive designs that enhance user experience, ensuring consistency across the entire application.
Supporting Large-Scale Apps
When your business starts to scale, so does the complexity of your digital platforms. Building a robust application for B2B website development can be a daunting task but ReactJS simplifies this process by breaking down the interface into smaller, manageable components.
As Vasyl Magometa, CTO and Co-founder of Reenbit, explains, "ReactJS’s component-based architecture promotes modular, reusable code for scalability and team collaboration.”
“Key features like concurrent mode and server-side rendering optimize performance, while hooks simplify state management,” he adds.
This combination makes ReactJS the go-to choice for large-scale applications.
“React’s ecosystem — including tools like Redux and Next.js — supports growth and maintainability, making it ideal for building complex, high-performance apps," Magometa concludes.
SEO-Friendly
In the race to the top of Google’s search results, having a fast and SEO-friendly website is crucial. While traditional JavaScript frameworks aren’t known for their SEO prowess, React’s server-side rendering (SSR) capabilities, often powered by NodeJS, ensure that your pages load quickly and are easily indexable by search engines.
This means your business is more likely to rank higher on Google, driving organic traffic and reducing the need for paid ads.
Performance Optimization
Time is money, and slow websites cost more than just frustration — they can lead to lost revenue. React’s use of the virtual DOM means it only updates the parts of the page that need it, avoiding costly operations that could slow down the entire application.
As Fabricio Defelippe, CEO of Tuxdi, explains, "In managing performance optimization for data-intensive applications with ReactJS, we focus on efficiency at scale. For handling large datasets, we rely on list virtualization with tools like react-window, ensuring smooth performance without overwhelming the DOM."
Additionally, Defelippe highlights the importance of efficient state management: "We minimize redundant updates using useReducer and leverage global state management tools like Redux to maintain performance as our applications grow."
These combined strategies ensure that even in the most data-heavy environments, React applications stay fast and scalable.
Cross-Platform Compatibility With React Native
Why spend double the time and money building separate web and mobile applications when React allows you to do both? React Native, a framework built on ReactJS, allows you to create mobile applications for iOS and Android using the same component-based approach.
This cross-platform capability provides your business with more flexibility while maintaining a unified user experience.
Reducing Technical Debt
Technical debt is the serial killer of software projects. It’s what happens when quick fixes and outdated code start piling up, making future development slower and more painful. React’s component-based structure encourages clean, reusable code, which helps reduce technical debt over time.
Victor Motogna, Head of Web Development at Wolfpack Digital, highlights the role of TypeScript and hooks in further minimizing technical debt: "I think the biggest part has been TypeScript support, setting a standard for using hooks and React components. TypeScript helps catch errors early and enforces consistent typing, significantly reducing runtime issues and long-term maintenance overhead.”
He then adds that “Establishing a standard for using React Hooks simplifies state management and side effects, making the codebase cleaner and more predictable over time."
Backward Compatibility
Technology upgrades can be a costly endeavor, especially when they disrupt existing systems. ReactJS offers excellent backward compatibility, meaning you can adopt new updates without overhauling your entire application. This reduces the risk of downtime and allows your business to stay agile and competitive while keeping maintenance costs low.
Longevity and Future-Proofing
React is supported by Meta and has one of the largest development communities worldwide. With thousands of web design tools, plugins, and extensions available, developers can supercharge their projects without reinventing the wheel. Its widespread adoption, frequent updates, and extensive ecosystem ensure that ReactJS will remain relevant for years to come.
For businesses, investing in a technology that is constantly evolving means future-proofing your applications and avoiding costly rewrites or migrations down the line.
When To Use ReactJS?
So, when should you use ReactJS? Well, React shines in several scenarios:
Single-Page Applications (SPAs)
If your business aims to build a highly interactive web app that delivers a seamless, desktop-like experience, ReactJS is an excellent choice. Think of platforms like Facebook, Instagram, or Gmail — applications where speed and an intuitive user experience are critical.
React’s ability to handle dynamic updates without full page reloads makes it ideal for SPAs, ensuring your users have a smooth and engaging interaction with your service.
Large-Scale Projects
When managing a complex, large-scale project that needs a modular and scalable approach, React’s architecture is invaluable. As we mentioned earlier, for businesses dealing with extensive applications that evolve over time, React allows to break down the app into reusable components.
This modularity facilitates easier management, scaling, and future enhancements, making it easier to adapt to growing demands and changes.
Real-Time Data Updates
For businesses that require real-time data updates, such as news feeds, live dashboards, or financial applications, React’s virtual DOM excels in maintaining performance. It efficiently updates only the parts of the page that have changed, preventing unnecessary refreshes and ensuring that your data is presented smoothly and promptly.
This capability is crucial for applications where timely, accurate information is essential to your business success.
Cost-Effective Solutions
When budget constraints are a concern, React’s efficiency can be a major advantage. Its reusable components and effective ecosystem of tools and libraries help reduce development time and costs.
Additionally, the ability to leverage React Native, as we mentioned before, for both web and mobile apps, further optimizes your budget by minimizing the need for separate development efforts for different platforms.
