Developers at Facebook and Instagram required special tools to build interactive, dynamic, user interfaces. React is not a language in its own right, nor is it a framework, it is simply a Javascript library used to create interactive components.

A component can be anything on a webpage that the user interacts with. It takes an action, and often input, and performs some function. A common example would be a search bar which begins to auto-complete or offer suggestions, based on what the user is typing. This type of functionality cannot be achieved with basic HTML. Before react it would have required some type of server-side programming.

React, in simple terms, in a Javascript library that allows the developer to easily and efficiently create dynamic components in a user interface. While many people have heard of react they may not be familiar with specific use case examples. Here we will look at just that.

Facebook, Instagram, And Netflix

As detailed above, React was created by developers at Facebook and Instagram to create interactive components within a user interface. The react library was made open source in 2013 and has become very popular since. While Facebook and Instagram continue to use React, other well-known products, such as Netflix have also begun implementing it in their user interface.

This should come as no surprise for most individuals since Facebook purchased Yahoo mail. “Yahoo mail required a great deal of updates on a regular basis. Many of the components were done using a Model View Controller pattern which is much more suited to smaller applications. Implementing React allowed for greater modulation and an easier time when it comes to updating the UI,” writes Ben Sheen, a web developer at Writinity and Lastminutewriting.

it should come as no surprise the React JS has been used in the simple, yet effective, chat app Whatsapp. This is because Facebook bought the application in 2014 for 16 billion dollars. “WhatsApp is one of the most widely used instant messenger applications in the world with billions of users. The single-page components are all built using the React JS library,” writes Andrew York, an IT expert at Draftbeyond and Researchpapersuk.

WhatsApp is an excellent example of just how widespread the use of the React JS library has become. Many of the components would have previously required an integration of HTML, CSS, Javascript, as well as novel server-side functionality to implement. React JS reduces the need for so many individual parts and provides a simple, streamlined, method of creating these components. For these reasons, many IT experts and enthusiasts expect React’s popularity to increase even further in the coming years. Another major aspect contributing to its popularity is its relatively easy in regards to use. Since it is not a new language or framework developers do not have to spend a significant amount of time learning the ins and outs of react.
