What popular websites are built with React

Among all the available frameworks, tools, and libraries, there is one that gained enormous popularity and good reputation – React. Its story began in 2011 when it was first deployed on Facebook’s News Feed and later, in 2012, on Instagram. Over the years, React has built up incredible respect and is used on nearly 4 million websites! See what popular websites are built with React.

What is ReactJS?

ReactJS is an open-source JavaScript library. Over the years, it has gained great and unflagging popularity. ReactJS is used to create graphical interfaces for web applications. It was developed by one of the Facebook developers and is still supported and maintained by the company to this day. It was created for the internal needs of the company, the company’s engineers were looking for a way to build dynamic but very efficient interfaces, which resulted in the creation of this universal library. The React developer, Jordan Walke, while creating it, was inspired by a library of HTML components for PHP, which is XHP. This library is most often used to create single-page applications, but it can also be the basis of mobile applications. Originally, React.js was intended only for internal projects, but in 2013 it was made available by Facebook on an open-source basis. Currently, React.js is one of the most popular JavaScript libraries for creating websites and web applications.

Why is ReactJS so popular?

React is a really powerful tool. It has many features that make developers often turn to this library. It is distinguished, for example, by the virtual DOM. React.js creates an in-memory data structure cache, computes the resulting differences, and then successfully updates the browser’s DOM display. This allows developers to write code as if the entire page was rendered with each change, while the React libraries only render the subcomponents that change. This significantly improves performance. What’s more, the React code is made up of components, i.e. fragments of reusable code. They are used for the same purpose as JavaScript functions, but operate in isolation and return HTML. This helps to write code faster and more transparently. It’s worth mentioning that ReactJS is relatively easy to learn. It has built-in formulas and functions that you can combine to create effective projects in less time than creating code line by line. Besides, you can start creating highly responsive applications with it right away. These and other advantages make developers very eager to use React.

10 famous ReactJS websites examples

Facebook
Undeniably the most famous and well-known social network in the world, Facebook, is opening our list. It could not be different as React was initially the company’s internal tool. The social platform at the beginning was meant to be used by Harvard students. As we all know, now it is the most popular social network, connecting people all around the world. Coming back to React, its creators obviously use its library in their products. They take advantage of React’s benefits to create a highly responsive, smoothly performing website, with a rich user interface.

What are the benefits of ReactJS?

To name just a few essential advantages among their large number:

  • Easy to learn – compared to other technologies of this type, learning ReactJS is considered easier. This is important for companies that want to develop their team, but also for novice programmers. Knowing the JavaScript syntax makes this process easier, and most JS programmers start with ReactJS, but it’s not necessary. With ReactJS, you can start building highly responsive applications in no time.
  • Faster rendering and good performance – virtual DOM makes React JS one of the most effective technologies for application development. DOM (Document Object Model) has a large impact on the potential load of the application due to its structure. Using a virtual DOM that is smaller and can be quickly updated improves application performance. Only after the site interacts with the virtual DOM is the actual DOM updated. As a result, it provides a better user experience, higher efficiency, and excellent performance.
  • Easy coding – among the useful ReactJS functions are also those that visualize what is happening in JavaScript code operating on graphical interfaces. JSX is used for this, i.e. an extension of the JavaScript syntax. It also helps React display more useful information about errors and warnings, makes it easier to render subcomponents, and accepts HTML quoting.
  • Extensive SEO capabilities – due to the current trends, this is a very important feature. JavaScript frameworks are usually not very SEO friendly, and web applications lose the position in search engines with optimized pages. The ability to react to common problems with search engines is another advantage of using the React JS framework.
  • Downstream data flow – there are many ways to reduce errors in your code, and the framework and library developers are aware of this. With ReactJS, one process that helps reduce errors in your code is one-way data flow, also known as downstream data flow. This means that data is only transferred between items in ReactJS in one way. This provides a more stable code and fewer bugs.
