React.js Development: Everything You Want To Know

14 March 2024 Writer: Lera Grechanik 399 views

Searching for the approach to utilize in the product realization, you may find out React.js web development is among the brightest stars in the sky of project building. But how to identify your wishing star?

For example, React Native vs React.js has more features and more ways where to apply, with React.js software development included.

In this blog, we would like to name the main characteristics of this technology you need to be acquainted with to make your decision.

React.js development


React.js (or simply React) is a JS library created by Meta to design user interfaces. It allows developers to build efficient, scalable, and supported web applications using a component approach.

React.js application development provides tools for scalable and fast web development with React and mobile app development using React.js, allowing engineers to focus on creating UI rather than on manipulating DOM or state management.

As soon as it works with the virtual Document Object Model, which is a virtual representation of the real DOM. When the component state changes, React creates a new DOM virtual tree and then compares it to the previous state. React then determines the minimum set of changes that must be made to the real DOM to update the interface and applies these changes.

This process makes the interface update more efficient and faster, as React minimizes the amount of actual changes that are performed in the real DOM. React also supports unidirectional data flow, making state management and interface updates more predictable and easy to debug.


As with any successful technology, React.js development services have their own features and benefits of React. Here are some features of React.js that make it a popular tool for web app dev:

  • Virtual DOM (virtual object tree)

  • Component architecture

  • JSX (JavaScript XML)

  • One-way traffic 

  • Status and life cycle of components

  • Expandability and ecosystem

In general, React.js development offers a simple and efficient way to create scalable and productive web applications with a high degree of reusability and coding support. So, those React.js features just underline the importance of this approach.


Based on all these features of React front-end development, it is possible to identify the main directions of the tasks that outsource React development helps to cope with. So here are several of them:

  • Declarative UI creation: It allows developers to describe the UI structure declaratively using JSX, making the code more readable and understandable.

  • Component architecture: React development tools split user interfaces into small, reusable segments. This allows developers to create clean, modular, and scalable code.

  • State Management: RJS provides mechanisms to control the state of an application, such as the local component state (useState) and the global state, by using context and managed state components through managed forms.

  • Life cycle: It provides different component life cycle methods that allow developers to perform specific actions at different stages of the component’s life cycle, such as when a component is created, updated, or deleted.

  • Roaming: Although it does not provide instruments for routing, there are side libraries, such as React Router, that allow you to manage navigation and routing in React-applications.

  • Server Rendering Support: It delivers server rendering capability, which allows you to create applications with a responsive interface and well-optimized SEO.

  • Ecosystem and Tools: Tools for React development have an extensive ecosystem of tools and libraries that simplify the development of web applications such as Redux for state management, Material-UI, and Styled Components to create a user interface, Axios to work with HTTP-requests, and much more.

These features make React.js for mobile app development a powerful and flexible tool for developing modern web applications.

Now let's slightly name the cases to answer the question of when is React.js development useful and when it is better to avoid it and choose another option.

Avoid using RJS for small projects with limited resources or requiring quick start-up, especially if you do not have experience with this tool, as well as when SEO has high priority and requires full indexing of the web search engine applications.


React.js for web development is attractive due to effective interface update, component architecture, declarative approach, extensive ecosystem, cross-platform support, server rendering capabilities, active development, and support of a large development community.


React for mobile development uses tools such as React Native or Expo. These allow you to create multi-platform applications using familiar React components and approaches. Libraries and tools, such as React Navigation and React Native Elements, facilitate the creation of user interfaces and navigation for React mobile app development.


Think that you already understand that this technology is so popular not by accident. All points that we have named above are contributed to the popularity of the method. The agility, embeddability efficiency, component architecture, declarative approach, extensive ecosystem, cross-platform, and support of large companies work hand-in-hand with the dev teams on every step.


React development tools are also the point of the popularity this technology has reached through the years of its life.

Here are some of them:

  1. Create React App: This is the official tool for quickly creating new projects on React. It provides an initial configuration, a local development server, and a project build for production.

  2. React Developer Tools: This browser extension allows developers to debug and analyze their React applications easily, providing access to components, their status, and context.

  3. Redux: Redux is the application status management library. It provides predictable state management, simplifies the debugging and testing of applications, and is the basis for creating complex applications with high state.

  4. React Router: This is the navigation library for cases. React Router provides powerful tools to manage routes and display various components depending on the URL.

  5. Material-UI: Material-UI is a user interface component library based on Google’s Material Design language. It provides ready-made components for creating stylish and modern interfaces.

  6. Styled Components: This library for creating stylized components. Styled Components allows you to embed styles directly into the component definition, making the code cleaner and more modular.

  7. Axios: It is a library for performing HTTP queries from JS code. It provides a simple and user-friendly interface for network queries and supports many features, such as error handling and interceptor installation.

  8. Jest and React Testing Library: To test applications, Jest and React Testing Library provide powerful tools for writing and running tests on components, hooks, and other parts of your application.


In conclusion, RJS remains one of the most popular and sought-after tools in web development due to its efficiency, flexibility, and extensive capabilities. In a world of fast and constantly evolving web development, it continues to be an indispensable tool for creating innovative and amazing user interfaces. Its component approach, virtual DOM, and active development community make it ideal for creating modern and productive web applications. Regardless of your programming experience, RJS each provides the tools to solve a variety of tasks and achieve your development goals. It makes this technology easy to learn and master for the newcomer in programming. With RJS in your arsenal, you are ready to meet any challenges and implement the most daring ideas. Success in your journey with RJS!
