It possesses fast rendering features and, above all, has a robust developer community, so React JS is thought of as the complete go-to solution for many businesses looking to build scalable, dynamic, and efficient web applications. With the increasing popularity of hiring React JS developers, the race has started among employers to outcompete one another in winning the high echelons of talent to keep in stride with a very dynamic environment in constant change.

Here, let’s explore how to hire React JS developers and understand their required skill set to the best possible hiring decisions with candidate evaluation. Whether you’re a startup, a mid-size company, or an enterprise, this guide, tips, and insights will bring you the perfect React JS developer-one who is not only skilled but fits your team perfectly as well.

Why You Need to Hire React JS Developers for Your Business?

So, now let’s talk about how people want to hire React JS developers and why hiring the correct ones is important for your business.

The Popularity of React JS

React JS is developed by Facebook. Its popularity has increased immensely. It is now one of the high-ranked, most-used JavaScript libraries in front-end development.  The popularity for which React JS has been favoured by the developers can be attributed to the following reasons:

• Declarative Syntax:  With React’s declarative syntax, it is going to be easy to create interactive UIs that update components when data changes.
• Component-Based Architecture: With React, developers can break an application into small, reusable pieces of a program. This way, the code will be more modular, manageable, and testable.
• Virtual DOM: The virtual DOM of React updates only those parts of the UI that need a change. React is faster in its performance compared with the traditional DOM.
• Huge Ecosystem: React boasts of this massive third-party library, tools, libraries, and extensions, which make it an easily adaptable framework for most use cases.

High demand and versatility make assurance of keeping the company in line with the latest web application development purely at your fingertips with skilled React JS developers.

Growing Demand for React Developers

The uptake of React JS adoption has been so fast that the demand for skilled developers has skyrocketed in every business in every industry. Many businesses today look for such React developers who can build responsive, high-performance web applications. Whether it is any e-commerce websites, dashboards, social media platforms, or enterprise applications, people rely on React JS for new front-end development.

According to LinkedIn‘s 2020 Emerging Jobs Report, React JS development belongs to the growth job categories within the technology sector, with more than a 50% growth year-over-year in available jobs.

This trend does not seem to slow down, which means employing employers must act quickly and be ahead of the game to attract and hire React JS developers into the company.

What to Look for When Hiring React JS Developers

But now that we know why hiring the best React JS developers is so crucial, let’s get into what are those key skills and features to keep an eye open for in that developer.

• JavaScript (ES6+)

React JS is built on top of JavaScript, and therefore an in-depth understanding of the language is utterly necessary for any React developer. We’d be looking out for “Modern” JavaScript (ES6+ features) are:

• Arrow functions
• Promises and async/await
• Destructuring
• Template literals
• Modules and classes

Having an excellent knowledge of JavaScript is important because it ensures developers write clean, maintainable, and efficient code.

• Experience with the React Ecosystem

React JS is the core library but there are several related technologies and tools that any developer working on React applications should know:

React Router: It’s a way to implement routing in single-page applications.

Redux or Context API: It’s a method of state management in large-scale applications.

React Hooks: Essential for React development, they manage the state and side effects within functional components.

JSX: A syntax extension that allows you to write HTML in JavaScript.

Webpack and Babel: Brought to you from bundling and compiling code, respectively.

REST APIs / GraphQL: Depending on the domain, a good React developer will have an understanding of consuming data from APIs as well as guiding the flow of data through the application.

Experience in such technologies will be the benefit of the candidates to create a complete, full-fledged React application.

• Knowledge of Frontend Development Tools

In general, front-end developers developing with React will have to interact with the following tools of frontend development:

Version Control Systems: Git knowledge will be mandatory for collaborative coding and tracking versions.

Task runners/build tools: Knowing NPM, Yarn, and Webpack is important for automating tasks and optimizing build processes.

Code quality tools: ESLint, Prettier, etc., to keep the same level of code

Testing frameworks: Knowledge of tools like Jest, Mocha, or Enzyme for unit and integration tests created by a React developer

These tools make the process of development more streamlined and ensure the quality of code in big projects.

• Problem Solving and Analytical Skills

A good developer with React JS should have very sharp problem-solving skills because problems are often complex while building dynamic and interactive web applications. The breakdown of the problem into smaller, manageable pieces will be designed by a good candidate, who will arrive at optimal solutions. Their ability to think critically and troubleshoot problems quickly will have a direct impact on project timelines and success.

•  Responsive Design Experience

With the growing mobile-first world, it is much more crucial to possess responsive and mobile-friendly applications today. Hence, React developers must master using CSS along with other CSS frameworks, such as Bootstrap, Material UI, or Tailwind CSS, so that their applications are responsive and work well in different screen sizes.

Know-how of CSS preprocessors like SASS and CSS-in-JS libraries like styled-components is a bonus.

•  Familiarity with Agile Methodologies

Due to the frequent release of updates, developing applications in React mostly happens in an agile environment. Teams will work in sprints, and keep continuous integration and release often. Experienced developers in agile methodologies will easily adjust to the workflow of your team, collaborate effectively and produce high-quality features.

1. Good Communication Skills

Good communication is good in any development role, but especially if you’re a React developer who spends lots of time collaborating with designers, and backend developers, and sometimes working one-on-one with product managers or stakeholders. Look for people who can clearly articulate their ideas, give updates, know how to ask a question when they need to and, ideally, can simplify technical concepts to communicate them to others.

Evaluating React JS Developer Candidates

Now that you have identified your required skills and qualities, it’s now time to evaluate candidates. Here’s how to fully evaluate React JS developers:

• Technical Interview

A technical interview will allow you to determine the amount of coding ability, problem-solving acumen, and knowledge of React your candidate possesses. You will want to ask questions of these types during the interview:

• Concepts about JavaScript: closures, scope, async programming
• About React concepts: components, state, props, lifecycle methods
• Manage state with Redux or Context API
• Worked with Hooks and how to apply them
• Manages form validation and API requests in React
• Optimized performance in React

You may also request them to explain their portfolio or share code snippets from past projects.

1. Coding Challenge or Take-Home Assignment

The extent to which the candidate applies his knowledge of React to real-world problems. A practical coding challenge or take-home assignment could be set to get them building a small React application fetching data from an API, to implement a feature such as authentication, or a to-do list; they could use that application to create a responsive layout or integrate state management.

Ensure that the problem examines their knowledge of React components, state management, and API integration.

• Portfolio and GitHub Profile

Scan a candidate’s portfolio or GitHub profile for an idea about his coding style, degree of devotion towards quality, and experience in open-source contributions. Check for:

•  React projects present an in-depth understanding of concepts
• Detailed documentation and commit messages
• Contemporary JavaScript features with best practices
• Open source contribution or activity in the React community

• Cultural Fit and Soft Skills

Assessment of your candidate, apart from the technical skills, should look for a cultural fit for your team. Behavioural questions must be asked, reflecting his or her teamwork and communication skills and capacity to take advice as well as troubleshooting. A good React developer is receptive to knowledge and learning, agile in handling changes, and a good team player in a cross-functional environment.

Conclusion: The Right Hire

In short, hiring React JS developers is strategic in the sense you’re hiring into your organization the best minds within your industry. Therefore, understanding the skills needed, effective assessment of candidates, and also a team working environment will instil an in-house development team with passionate experts on React to drive the true success of your web applications.

The competition for skilled React developers is fierce, so act fast and offer competitive salaries while building an appealing work environment that attracts the best talent. Whether it is junior, mid-level, or senior development talent, following these tips will help you hire React JS developers for your company successfully in the fast-paced React development arena.
