React test
Summary of the React test
Our React assessment test measures developers’ skills in the React.js library. It evaluates candidates in the most important React concepts, as well as assessing their skill and familiarity with advanced concepts.
Covered skills
React Hooks
State Management

Advanced Concepts
Use the React.js test to hire
Front-end developers, full-stack developers, game programmers, React coders, social media specialists, and any other role that requires a good grasp of React.
About the React assessment test
React, or React.js, is an open-source JavaScript library that programmers use to build segments of an accessible user interface (UI).
Our Reactjs skill test evaluates candidates on the most important coding concepts, such as:
Using props and proptypes
Optimizing performance in React.js apps
Creating DOM elements
Using JavaScript expressions as props
The test’s multiple-choice questions ask candidates to explore different types of code, decide the outcome of specific React commands, and decide which coding actions they should take in realistic scenarios.
People who score well in the React.js test are knowledgeable about React’s limits and potential, competent in using different React tools, aware of how to maintain and improve UI through code, communicative and collaborative as part of larger coding teams, and confident working on their own projects.

The test is made by a subject-matter expert
Mohamed N.
A full-stack developer with over four years of experience, Mohamed has helped design and implement various progressive web applications mainly using React, Node.js, and the Java framework Spring. His main objective on any project is to develop high-quality applications with a flexible architecture that are both fast and secure. When not developing new apps, Mohamed actively contributes to many open-source projects and has published his own React and Javascript libraries.
Crafted with expert knowledge
TestGorilla’s tests are created by subject matter experts. We assess potential subject-matter experts based on their knowledge, ability, and reputation. Before being published, each test is peer-reviewed by another expert, then calibrated using hundreds of test takers with relevant experience in the subject. Our feedback mechanisms and unique algorithms allow our subject-matter experts to constantly improve their tests.
What our customers are saying
TestGorilla helps me to assess engineers rapidly. Creating assessments for different positions is easy due to pre-existing templates. You can create an assessment in less than 2 minutes. The interface is intuitive and it’s easy to visualize results per assessment.
VP of engineering, mid-market (51-1000 FTE)
Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.
The TestGorilla team only offers useful insights to user challenges, they engage in conversation.
For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.
I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.
For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

Why are React skills important to employers?
Employers hire React coders to run some of the web’s largest, fastest, and most intuitive apps, websites, and user interfaces. They keep end users happy, engaged, and invested.
By hiring React developers with the right technical skills, firms can create large web applications that change data without reloading the page, making code editing, troubleshooting, and problem-solving quick and easy.
What’s more, talented React experts bring several important skills to development teams:
Accountability: Reactjs programmers own their code and account for how it affects broader projects
Attention to detail: Reactjs developers pay attention to the smallest details when writing their code since even minor mistakes can cause malfunctions
Good communication: Reactjs developers often do pair programming, and good communication is important for working well with others on these projects
Learning ability: Programming languages change fast, so if a developer doesn’t constantly learn and adapt, their skills become outdated
4 React competencies to look for
When you test React skills, you measure candidates’ competency with:
React hooks: Can the applicant develop custom rules and create and use hooks (like useState and useEffect) without disrupting state in React applications?
State management: Can the candidate show how to structure state effectively, share state between different React components, and extract and reset state where needed?
React props: Can the applicant use props to move data between components?
React lifecycle: Does the candidate understand the four stages of React development – initialization, mounting, updating, and unmounting?
Testing for technical coding skills instead of relying on resumes helps hiring managers hire better-quality candidates. SiddhiSai Web Solutions, for example, started using TestGorilla to reduce bad hires. Thanks to skills testing, the company now hires more qualified developers much faster.
What job roles can you hire with our React test?
React coding is extremely versatile, meaning you can use our React.js online test to hire developers across different industries. For that reason, we’ve designed the test to be flexible.
Here are a few roles where React skills come in handy.
Front-end developers create website and app design elements from scratch using different coding languages, often in React
Full-stack developers build the front and back ends of a website through code – i.e., the user-facing side and the processing and storage elements behind the scenes
Game programmers produce interactive games and apps using complex code and make efficient edits against tight deadlines
React coders build and maintain UIs for apps and websites using React segments
Social media specialists use React to fix usability issues like infinite scroll problems, and React skills show a deeper understanding of how social media and apps function
Create a multi-measure assessment: 4 tests to pair with the Reactjs skill test
With TestGorilla’s talent discovery platform, you can build multi-measure assessments to test up to five of your candidates’ skills during the hiring process. It’s an excellent way to understand your applicant’s capabilities without relying on resumes.
Alongside our React assessment test, consider using the following tests:
React Native test: Test applicants on their skills using React Native rules and best practices and their ability to build and manage Native apps. Hire a programmer who knows more than React’s fundamentals.
JavaScript (Coding): Entry-Level Algorithms test: Hire React coders who can program basic Java algorithms. People who score well on this coding test clearly understand JS foundational principles. Consider using our JavaScript (Coding): Debugging test for specific developer roles.
HTML5 test: Find candidates who understand how to use HTML to build modern, highly scalable websites. Applicants who pass this test know how to format and maintain apps using advanced techniques.
Communication test: Measure candidates’ ability to actively listen to and work with others, verbally and in writing. Hire a communicative coder who supports and understands their team’s needs.
