According to Wikipedia, “React (also known as React.js or ReactJS) is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies.

React can be used as a base in the development of single-page or mobile applications, as it’s optimal only for its intended use of being the quickest method to fetch rapidly changing data that needs to be recorded. However, fetching data is only the beginning of what happens on a web page, which is why complex React applications usually require the use of additional libraries for state management, routing, and interaction with an API.”

1) Battle-tested

Its won’t be an over-estimation to say that Facebook is the largest social media network in the world and React is at the heart of it, with a team of dedicated developers contributing and improving it incessantly. Some other platforms built using React includes Netflix, Twitter, Uber, Airbnb, Dropbox etc. Its obvious that nothing gets bigger than the brands mentioned here. As a project manager or CTO, it’s reassuring and fulfilling to know that the technology you are going to recommend to a client (or in some cases client recommending it to development team) is at a very mature stage and there is a thriving contributor community.

2) Highly efficient

The perspective of ReactJS, where it develops its own virtual DOM for the components to reside in, provides the developer with a higher degree of workability, while improving the performance by a notch. This is due to the fact that ReactJS predicts through calculations the kind of modifications needed in the DOM environment and the trees are updated accordingly, making it cost-efficient and overall very flexible.

3) SEO friendly

JavaScript frameworks have never been SEO friendly (although admittedly there have been some advancements and workarounds in this area very recently), not until the emergence of ReactJS. As mentioned above, ReactJS can be run on the server, which in turn will give back the virtual DOM and then rendering is done in the form of a regular 1 page website. Very simple, right???

4) Based on mostly plain JavasScript

If there is a situation where you need to scale up your React team and you only have simple JavaScript developers left to be included in the React team. In such a scenario, it won’t be a time-consuming and effort-intensive affair as it doesn’t have a large API structure. Another factor is JSX, which is used in React JS, is a perfect combination of JavaScript and HTML.

5) Simple yet unconventional

There are so many browser extensions available now-a-days for easy debugging of an application built using ReactJS. What really makes this interesting is that the virtual DOM can be easily viewed just like viewing a conventional DOM tree in the element’s panel.
