A brief history of React.js
The inception of React.js began in 2011 when Facebook engineers noticed some performance issues caused by a sharp rise in the number of users. They embarked on a fresh news feed or exclusively a dynamic news feed, leading the way to the creation of React.js.

In 2013, Facebook open-sourced it; since then has come a long way from where it all started. To gain a deeper understanding of their remarkable achievements, we would explore some intriguing popularity statistics.

As per a report by Statista, It was the second most used front-end development technology in 2022, overtaking jQuery, with 42% of developers reported to be using it.

It has over 204k stars on GitHub and over 1500 contributors.
Over 10 million companies across the globe are using React.JS. This number also includes some of the biggest and most influential tech giants that we will delve into throughout the course of this article.

ReactJS development allows developers to build interactive, responsive web applications with reusable components. This is why it is hailed as one of the most powerful JavaScript libraries in the current era for developing modern web applications. And there are several factors that made it a popular JavaScript library. Below are a few of them:

Declarative: Since it is declarative, that provides a very simple way to develop interactive user interfaces.
Reusable components: The component we code using React.js can be reused, thus breaking complex logic into multiple smaller parts.
Virtual DOM: With react, we usually communicate with the virtual DOM (a copy of DOM saved in memory), which improves the application’s performance as it works by activating the individual component on the virtual DOM instead of reloading the whole page.
React.js is easy to grasp: Nowadays, simplicity and the learning curve are significant factors behind programming language growth.
A great number of pre-built libraries: It has so many pre-built libraries that can speed up development time.
Strong community support: React has a huge community of developers, so you can collaborate and get help from supporters around the world.
React.js – A Powerful JavaScript Library to Build Interactive UI
In simple terms, React.js is one of the most popular JavaScript libraries that is used to build dynamic interfaces and interactive elements on web pages. It boasts features that help in developing the UI where only necessary web components load or render when a user interacts, bypassing the full page loading, thus enhancing the overall performance and speed of the website.

It has got some blazing-fast rendering capabilities that make it one of the most-preferred Javascript libraries among developers and tech-giant. This is why it has been adopted by many biggies mentioned in the list below.

1. Facebook

Facebook is the world’s biggest social platform, with over 2.9 billion users. It partially uses ReactJS blended with other technologies on its web application. Interestingly, ReactJS was created by a Software engineer – Jordan Walke– a software engineer at Facebook, and later implemented on the Facebook web application.

By injecting ReactJS, enhancing user experience, and bringing more interactive features onboard, they eliminated the traditional news feed, which used to force the page to reload every time users interacted with in-page elements.

1. Instagram

Instagram is one of the most popular social media platforms that allow you to share photos and videos and connect with millions of users across the globe.

This is another app that deployed ReactJS in its front-end development. Instagram’s web page is developed using React and Backbone.Router. Features like geolocations, Google Map APIs, and accurate search results are some examples that show the significant amount of usage of ReactJS by Instagram.
