Overview
ReactJS is an open-source front-end JavaScript library for building user interfaces for web applications. Meta and a community of developers and companies run and maintain it. Launched in 2013, React is one of the most extensively used front-end libraries for web development. It includes different extensions that help provide architectural support for entire applications: Flux and React Native, to name a few. Some of the world's leading companies, such as Airbnb, BBC, Meta, etc., leverage the functionalities of React.js because of its stability, scalability, and efficiency.
React.js has become a hot favorite amongst developers due to its ease of developing websites and apps. Listed below are some reasons behind its popularity:
- Provides flexibility and scalability
- Cost-efficient

With features galore, it is safe to assume that most fortune 500 companies would choose to use React as their go-to tool. Also, most developers prefer ReactJS for front-end development.
However, organizations can only harness the potential of React's advanced library if they have a diverse, flourishing team of talented ReactJS developers. These professionals must have desired skills and technical exposure to understand organizational needs, helping them translate the business needs to technical specifications. However, we also cannot rule out the fact that there is an urgent requirement for well-versed, highly competent professionals in this sector.
