ReactJS is an open source JavaScript library designed by Facebook for creating rich and engaging web apps fast and efficiently with minimal coding.
The core objective of ReactJS is providing the best possible rendering performance using The Virtual DOM.
Its strength comes from the focus on individual components , so Instead of working on the entire web app, ReactJS allows a developer to break down the complex UI into simpler components.

![React-benefits-1-1024x576](https://dev-to-uploads.s3.amazonaws.com/i/se2lt084f3u1mbngh6rt.jpg)
 **1-React has an awesome community**
One of the most preferred reasons to learn React JS is its popularity. And with popularity comes a wide community to help new developers.

**2-React is SEO-friendly**
React is widely recognised as the friendliest JavaScript library for SEO purposes. While React in itself isn’t SEO-friendly (like all JS frameworks), React embraces SEO and its components are easier for Google to crawl.

**3-React is very scalable**
The very first and main evidence of the React JS scalability is Facebook itself.
It's made entirely on React JS and has over 50,000 different components. And it's still growing without any performance problems!

**4-React is all about Reusable Components**
React saves you time and money on development because it’s component-based. You can break down an interface into reusable components that allow you to build dynamic user interfaces.

**5-React’s Performance is Amazing**
High performance is critical for web applications. 47% of people expect a webpage to load in 2 seconds or less. Additionally, 33% of your userbase will abandon your website if it takes more than 10 seconds to load.
Businesses that use ReactJS are assured of better performance compared to those that use other frameworks.
React is using a virtual DOM, which means it doesn’t have to generate all the HTML files from the bottom to the top, whenever the change appears.
Instead, he looks for the differences between the current and the old HTML and updating it accordingly, making all the loading experience feels like a blink of an eye.

**6-Development Speed**
React been also built with developers in mind.
The coding itself allows you to create web and mobile apps way much faster than any other framework.
The great advantage of React is that you can just code it once, and use it on the different platforms. You can hire one good React developer and he will be able to build web apps, mobile apps, and even apps for a tablet.

**7-Backward Compatibility**
Still, none of the other frameworks is able to be so easily compatible.
If you use Angular, there is a big chance that instead of upgrading it to the new version you will have to write your app from scratch with the new public API.
Whenever a new version of React is coming out, the public API remains almost totally the same. This helps Facebook refresh it’s code and still be able to work on his old pieces at the same time.
In other words, you don’t have to learn React again and again after each and every launch, and you can be sure your older version remains compatible with all the new components.

You can think and imagine the future of ReactJS by yourself after knowing the large and most popular companies names that use React.

#Conclusion
Each and every technology seems to have the same goal – doing things easier, faster, and ultimately better.

Learning **ReactJS** is the need of the hour and makes sense as it is providing much-needed ease to developers in building highly engaging web applications and user interfaces in very lesser time, where they create large scale apps with frequently changing data.
