What is React.js, and how does it work?

If you think of web development as building with a LEGO set, React.js is the Millennium Falcon. It's an open-source JavaScript library perfect for crafting modern, interactive UIs. How? It breaks down web pages into smaller components (think buttons or input fields) that can be used again and again. Less coding, more creation!

Special features of React.js

  • Reusable Components: Build once and use everywhere. Less code, faster development.

  • Virtual DOM: This speedy feature only refreshes parts of the UI that have had a makeover. As smart and speedy as Falcon's response time!

  • One-way Data Binding: This ensures that one component's mood swing doesn't mess with another's. Translation? Easier debugging and a neat codebase.

  • JavaScript XML (JSX): Imagine writing React components with a sprinkle of HTML-like syntax. It's the familiar touch of JavaScript, but jazzed up!

Problems solved by React.js

  1. Building reusable UI components: Update one, and only the changed parts freshen up. Sharing across projects? Easy.

  2. Enhancing existing apps with dynamic user interfaces: Boost existing apps with modern features without needing a full rebuild.

  3. Managing application state: Ensure everything runs in harmony, from user data to real-time content changes.

  4. Collaborative development: Keep everyone on the same trajectory, creating a consistent and united front.

When to Avoid React.js:

  • For very basic UIs, React.js might be overkill.

  • If you're unfamiliar with JavaScript, other web frameworks offering simple HTML templating might be more suitable - unless you're able to work with an expert development team like NaNLABS.

Top Use Cases and Examples of React.js 

React.js has proven its worth in various applications, enhancing front-end development for both mobile and web platforms. Here are some notable examples you might have heard of:

#1 Marketplace: Airbnb utilizes React.js for dynamic search capabilities and has even extended its benefits to mobile through React Native.

#2 Virtual Realty: Transported offers immersive 360° property tours. With React.js, they've crafted a seamless navigation similar to Google Maps.

#3 Enterprise Software: Atlassian, the genius behind Jira and Trello, harnessed React.js for its cloud-based platform, ensuring a consistent UI and efficient code reuse.

#4 Photobook Editing: Artifact Uprising boasts a drag-and-drop editor for customizing photo books. React.js guarantees a smooth, adaptable interface.

#5 Social Media Giant: Facebook (now Meta) was at the inception of React.js. Its news feed leverages React to render dynamic content, with the mobile application relying on React Native.

#6 Risk Management: CyberCube, a cyber risk platform, transitioned from Angular.js to React.js to enhance user experience across its product suite.

#7 Streaming Service: Netflix adopted React.js to refine its UI performance across various devices, ensuring consistent user experience.

#8 Sales Tool: Equinix, a global data center, collaborated with design studio Secretly Nice and NaNLABS to craft a potent sales platform using React.js, which significantly boosted user retention.

React.js Frameworks for Building Modern Web Applications

Developing with React.js alone is like flying the Millennium Falcon without ever engaging its hyperdrive. Instead, arm your team with one of these top React.js frameworks to transform your website into a hyper-speed vessel capable of navigating the vast expanse of the modern web galaxy.

  1. React Native: Ideal for building native mobile apps, offering features like cross-platform development and hot reloading.

  2. Next.js: Enhances app discoverability by web crawlers through server-side rendering. Ideal for businesses wanting SEO-friendly websites.

  3. Gatsby: Known for creating super-fast websites, perfect for growing businesses aiming for peak performance.

  4. Grommet: Focuses on design, providing a rich library for crafting compelling user interfaces.

  5. React Bootstrap: Facilitates quick UI development using Bootstrap's design conventions in React components.

Now you have a brief overview of what each framework does, let’s compare.

React vs. Angular 

When deciding on the tech stack for your next project's front-end tools, two major players come to mind: React and Angular. Both aim to assist developers in creating outstanding web application user interfaces (UI), but they have distinct features that cater to different requirements.

React.js overview

A library that offers a great degree of flexibility and control.

Key Strengths:

  • Flexibility: As a library, React offers more freedom, allowing developers to pick and choose features without being bound by a strict structure.

  • Performance: The virtual DOM ensures efficient rendering, resulting in high-performing apps.

  • Cross-platform: Alongside React Native, React can power both web and mobile apps.

  • Community: A vast developer community provides continuous support.


  • React.js starts minimally, often requiring users to select tools for each development, which can be daunting for beginners due to the large variety of libraries with similar functionalities.

  • Requires additional tools for features like routing and AJAX calls.

Angular overview

A comprehensive framework built with TypeScript.

Key Strengths:

  • Structured: Being opinionated, Angular provides a clear path for designing apps, ideal for large teams and projects.

  • Integrated Tools: Comes with a suite of built-in libraries and a command line interface.

  • Two-way Data Binding: Changes in HTML or TypeScript code are automatically reflected.


  • Two-way data binding can sometimes cause performance issues in large apps.

  • Its strict structure can sometimes limit flexibility.

  • Can be overwhelming for beginners due to boilerplate code and frameworks.

React vs. Angular: Which to choose?

While NaNLABS typically leans towards React due to its flexibility and control, Angular's structured approach makes it a top choice for robust, scalable applications. Your choice between them should align with the project's requirements and team expertise.

Choose React If you prioritize flexibility, interactive UIs, and cross-platform development.

Choose Angular If you need a structured framework suitable for large teams or extensive projects.

If in doubt, consulting with a software development company can provide clarity.
