React JS is one of the most popular JavaScript libraries available today. It’s an open-source library released by Facebook to help build single-page applications, and its popularity has only continued to grow since its initial release in 2013. As one of the most sought-after skills on Indeed, it’s important that you understand how React JS works and why you need to know about it if you want to be considered an excellent developer.

1) What Is ReactJS?

ReactJS is an open-source Javascript library for building user interfaces. Unlike other JavaScript UI libraries, React was built with one core principle in mind: Virtual DOM. The goal of React was to make it easy for developers to create reusable UI components that could be rendered on-the-fly by leveraging virtual DOM. There are two main reasons why you need to know about ReactJS in 2017.

First, Facebook will continue investing significant resources into its core infrastructure projects like ReactJS, which means there will be more job opportunities in 2017 than ever before. Second, if you aren’t currently familiar with how modern frontend development works (ReactJS included), then you might already be out of date when it comes time for your next career opportunity.

But what does ReactJS actually do? Well, there are three main benefits that make ReactJS an effective tool for building user interfaces. First, it uses a declarative programming paradigm that allows you to build dynamic UIs using simple HTML-like syntax. Second, since it’s fully component-based, it allows developers to create reusable UI components that can be used in any number of different projects. Third, its virtual DOM implementation makes it much faster than traditional JavaScript libraries like jQuery.

2) How Does ReactJS Work?

One of React’s biggest benefits is its use of a virtual DOM, which creates a much more efficient workflow for HTML rendering. As users interact with your website or application, React doesn’t go back to update individual parts of an HTML page (which would be time-consuming); instead, it compares what’s there with what it expects will be there (which it learns from its local reactive state), then efficiently updates only those elements that have changed. This lets you build applications that load almost instantly—and even better, don’t bog down as more content or other features are added. What makes all of this possible? Well, that would be ReactJS!

3) Benefits of ReactJS

When it comes to picking a JavaScript framework, your options are pretty big these days. On one end of the spectrum, you have libraries like jQuery or Backbone.js, both of which are top-level frameworks that work alongside other libraries. On another end of the spectrum, you have microframeworks like ReactJS, AngularJS, MeteorJS, EmberJS—which are standalone packages for rendering views in your web app. ReactJS stands out among its peers because it’s developed by Facebook (if that doesn’t give you some indication about its popularity then I don’t know what will). Currently trending in tech communities like GitHub and Hacker News—it appears that React is not going anywhere anytime soon.

4) Use Cases

React.js has tons of use cases, which you can find listed on their website . On its own, React is simply a view library. However, you can use it in conjunction with other libraries or even frameworks like AngularJS . Some common uses of React are creating content management systems, real-time applications, dashboards, interactive maps/screens/websites , etc. If your application’s user interface elements are completely static (i.e., they never change), then you don’t need something like React at all! You just need a framework that will let you display some text on a page.

5) Conclusion

The React library for rendering user interfaces is an exciting new option that’s not going away. If you want to take a look at React, it’s time to get up-to-speed—and we can help!
