Why React JS is a Must-Have for Your Business in 2025
React JS has emerged as one of the most powerful and popular JavaScript libraries for building user interfaces, particularly for single-page applications (SPAs). React’s flexibility, performance, and developer-friendly ecosystem make it the go-to choice for businesses looking to create interactive, high-performance applications.
As we move into 2025, hiring the right React JS developer is crucial for ensuring the success of your web development projects. But with a rapidly growing tech landscape, how can you ensure you are hiring the best talent to meet your needs?
1. Solid Understanding of Core React Concepts
The first and foremost thing to look for in a React JS developer is a strong understanding of the core concepts of React. These include:
JSX – The syntax that looks similar to HTML but is used in React to describe UI elements.
Components – The building blocks of React applications that allow for reusability and modularity.
State and Props – Two key concepts for handling data flow within React apps.
React Hooks – useState, useEffect, and custom hooks, which allow developers to manage state and side effects in a functional component.
In 2025, modern React development increasingly emphasizes functional components and hooks, so make sure your candidate is comfortable with these concepts.
2. Expertise in JavaScript and ES6 Features
React JS is built using JavaScript, so your developer must be well-versed in the latest JavaScript (ES6) features, such as:
- Arrow functions
- Destructuring
- Template literals
- Modules (import/export)
- Async/Await for asynchronous operations
A solid understanding of modern JavaScript will allow the developer to write cleaner, more efficient code and integrate easily with React’s functional components.
3. Strong CSS Skills and UI/UX Understanding
Since React JS is heavily used for building dynamic and interactive UIs, a good React JS developer should also have a strong understanding of CSS and UI/UX principles. Here is what you should look for:
Responsive design – Experience with media queries and frameworks like Bootstrap, Tailwind CSS, or Material UI.
CSS Preprocessors – Knowledge of SASS or LESS.
CSS-in-JS – Familiarity with styling solutions like styled-components or emotion.
Accessibility – Understanding WCAG guidelines for creating accessible web apps.
A solid design sense and the ability to create responsive, user-friendly layouts are crucial in delivering high-quality user experiences.
Pro Tip: Review the candidate’s previous projects to assess their UI/UX skills and their ability to build responsive layouts.
4. Familiarity with State Management Libraries
As applications grow in complexity, state management becomes a critical aspect of React JS development. A skilled React JS developer should be comfortable with state management libraries, such as:
Redux – A popular state management library for handling application-wide state.
Context API – React’s built-in solution for managing state across components without third-party libraries.
MobX, Recoil, or React Query – Modern alternatives for handling state more efficiently.
Ask candidates about their experience with state management and how they handle complex state scenarios in large applications.
Pro Tip: Inquire about how they handle state management in large-scale applications and their preferences for tools like Redux Toolkit.
5. Experience with Testing React Applications
In 2025, writing robust tests is a must for ensuring the reliability and maintainability of React applications. Look for developers who are comfortable with testing frameworks and libraries such as:
Jest – A JavaScript testing framework often used in conjunction with React.
React Testing Library – A library for testing React components that focuses on how the components behave from a user’s perspective.
Cypress – For end-to-end testing of React apps.
Testing ensures that the application runs smoothly and is bug-free after updates, making it an essential skill for any developer you hire.
Pro Tip: Ask the candidate to describe a recent project where they set up unit testing or integration testing for a React application.
6. Knowledge of Version Control (Git)
A React JS developer should be familiar with version control tools like Git and platforms such as GitHub or GitLab. Knowledge of version control is critical in collaborative environments, ensuring code changes are tracked and merged effectively.
Ensure the developer is comfortable with:
Creating branches for feature development.
Merging pull requests and handling conflicts.
Using Git workflows such as Gitflow for managing releases.
Pro Tip: Have the candidate demonstrate their workflow using Git to show their proficiency in branching and collaborating on code.
7. Excellent Problem-Solving and Communication Skills
Apart from technical proficiency, strong problem-solving and communication skills are equally important. React JS development often involves debugging, optimizing performance, and finding creative solutions to complex problems. A good React developer should:
- Break down complex problems into manageable tasks.
- Clearly explain their approach to solving issues.
- Collaborate effectively with other team members, including designers, backend developers, and project managers.
Pro Tip: During the interview, ask the candidate to explain how they have solved a challenging problem in a previous React project.
