Here are some scenarios where using React.js is beneficial and situations where other alternatives might be more suitable:

when to use React.js:

• Building dynamic web applications: React.js excels at creating dynamic and interactive user interfaces. If your project involves frequent UI updates, complex state management, or real-time data, React's component-based architecture and virtual DOM can provide significant benefits.
• Single-page applications (SPAs): React.js is well-suited for building SPAs where all content is loaded once, and subsequent changes are handled dynamically without full page reloads. React's efficient rendering and state management make it an excellent choice for SPAs.
• Large-scale applications: React's component-based architecture and modularity make it an excellent choice for large-scale applications. It allows for code reuse, maintainability, and easier team collaboration.
• Mobile app development: React Native, which is built on top of React.js, is a popular framework for developing cross-platform mobile applications. If you're targeting iOS and Android and want to reuse code and skills, React Native can be a great choice.

when not to use React.js:

• Simple static websites: If your project is a simple static website with minimal interactivity, using React.js may introduce unnecessary complexity. In such cases, static HTML, CSS, and JavaScript can suffice without the need for a full-fledged library or framework.
• SEO-centric websites: While React.js can be made SEO-friendly, it requires additional effort and configuration. If your project heavily relies on search engine optimization (SEO) and server-side rendering is a priority, other frameworks like Next.js or traditional server-side technologies may be more suitable.
• Tight deadlines or small projects: React.js, with its component-based architecture and learning curve, may require more time and effort to set up and get started compared to simpler frameworks or libraries. If you have tight deadlines or a small-scale project, a lightweight alternative like jQuery or vanilla JavaScript may be more appropriate.

It's essential to assess your project's specific requirements, complexity, team expertise, and long-term goals before deciding whether to use React.js or explore other alternatives. Working with EPAM Startups & SMBs, you’ll have our technology experts and consultants to back you up.

Here are some of the top React.js libraries and frameworks that you might find useful for your projects:

1. Redux: Redux is a predictable state container that helps manage the application state in a centralized manner. It works well with React.js and provides a clear and efficient way to handle complex state management.
2. React Router: React Router is a popular routing library for React.js. It allows you to handle client-side routing and navigation in your React applications. It defines routes in a declarative way and maps them to specific components.
3. Axios: Axios is a widely used HTTP client library that simplifies making asynchronous HTTP requests from your React applications. It provides an easy-to-use API for sending requests, handling responses, and managing interceptors.
4. Material-UI: Material-UI is a UI component library that follows Google's Material Design principles. It offers a rich set of pre-built and customizable UI components, making it easier to create visually appealing and responsive user interfaces.
5. React Bootstrap: React Bootstrap is a library that combines React.js and Bootstrap, a popular CSS framework. It provides a set of reusable UI components that are built on top of Bootstrap's styles and functionality.
6. Formik: Formik is a form management library for React.js applications. It simplifies the process of building and validating complex forms, handling form state, and managing form submissions with ease.
7. Next.js: Next.js is a full-featured framework for building server-rendered React applications. It provides server-side rendering, automatic code splitting, and simple routing, making it an excellent choice for building SEO-friendly React applications.
8. Gatsby: Gatsby is another powerful framework that combines React.js with modern web technologies to build fast and optimized websites. It offers features like static site generation, serverless functions, and data sourcing from various CMSs.
9. React Query: React Query is a library for managing remote data in React applications. It simplifies fetching, caching, synchronizing, and updating server data, providing a seamless experience for handling data-driven applications.
10. Styled Components: Styled Components is a CSS-in-JS library that allows you to write CSS code within your JavaScript files. It enables you to create and style React components using a component-based approach, improving encapsulation and reusability.

A React.js developer plays a crucial role in designing and developing web applications using the React.js library. Their responsibilities and tasks typically include:
