What to look for in React developers

React is a JavaScript library used for building user interfaces, specifically for single-page applications. Sometimes referred to as ReactJS, it is designed to easily integrate with existing code or other libraries. Its primary purpose is to simplify the development of web applications to make the process fast and simple, with less coding required. It is worth noting that React and React Native are not one and the same. To recruit a React developer you should be prepared to pay competitive rates. Here’s what else you need to know.

The most obvious skill to look for in a React developer is a thorough understanding of React itself. Beyond this, React uses JavaScript XML (JMX), an extension that allows HTML to be written in React. Many developers share the view that JMX is hard for junior developers to understand, so if your candidate can demonstrate proficiency in JMX it will be a big plus point.

Other desirable skills to look out for are experience with common front-end development tools and familiarity with code versioning tools. It will be helpful if they can demonstrate strong problem-solving and troubleshooting skills, as well as project management experience.

Hvad synes kandidaterne om DevSkiller-testene?

The regular feedback we receive from developer candidates is overwhelmingly positive. They love the structure of DevSkiller React coding tests and how well they reflect the real work that React developers do. Candidates relish the chance to prove their actual software development skills, rather than being expected to remember algorithms they haven’t touched in years. They also like the fact that DevSkiller tests use normal coding tools and conventions like unit testing, and cloning to GIT from a personal IDE.

If developers seem apprehensive at first, we find that it is because they are suspicious of academic algorithmic tests that don’t assess the actual skills that developers use day today. Once they realize that our React coding tests are different, they appreciate the difference and the fact that they can prove their skills in a fair setting.
