Top 6 technical assessment tools to vet a ReactJS Developer

According to Stack Overflow’s 2021 survey, React is not only the most extensively used web framework this year but also the most wanted, desired by one in every four developers. Moreover, 8000+ companies, including Instagram, WhatsApp, Yahoo, and Dropbox, are empowered by ReactJS. With the demand for ReactJS visibly growing and the talent pool limited, it’s no surprise that a successful recruitment drive may require external assistance. It can be time-consuming and difficult to vet developers by yourself, therefore, tools to vet a ReactJS developer comes into the picture.

These tools have been compared based on the following criteria:

• Types of Coding tests
