React.JS is an open-source JavaScript library for building interactive user interfaces. In this JavaScript library, web and computing professionals can access existing code pre-written from the JavaScript language to develop web components that users interact with on a device.

Because React.JS is open-source, it enables learners interested in web-related careers to provide efficient, cost-effective services to clients and employers. While helping learners enhance the services they provide, React.JS also helps them drive their value as professionals—in 2019, the average React.JS developer salary in the U.S. was $120,000 or roughly $57 per hour.

Resources across the web point to React being a good skill to know, with one revealing that learning React.JS is “the need of the hour.”

Because of React.JS’ relevance in the market, it’s safe to say this tool helps learners become more in-demand. Some job titles enjoyed by successful React.JS learners include Front-end Developer, UI Developer, Computer Programmer, Software Developer, Web Developer, Full-Stack Developer, Software Engineer, and others that are related.

Through Coursera, React JS is covered in various courses. These courses focus on understanding ways to create hybrid mobile applications; learning to implement NoSQL databases using MongoDB; communicating to the client side through a RESTful API; and more. Lessons are administered via video lectures, readings, quizzes, hands-on projects, and additional content.
