React is an open-source front-end javascript library for building user interfaces. The abbreviation 'js' in its name stands for JavaScript. React JS allows you to create complex user interfaces using reusable components. A significant advantage of this solution is that the developer no longer has to rewrite the same lines of code manually and instead can use previously created and saved components.

React js is a front-end technology, which means that it is responsible for the view layer - everything that your future user sees on his screen while using your web application. The nature of the Javascript language on which React JS is based means that the web application created with its help constantly refreshes the user interface data. If necessary, you can change the data without the need to refresh the web browser. It boosts performance and user experience.

If you are still not sure about the use of React JS, take a look at its benefits!

Strong Community

It's been over 8 years since the initial release of React JS, but Mark Zuckerberg's engineering teams still support it. The fact that it is a technology based on the popular JavaScript language causes the learning curve of React JS to go up very quickly. It means as much that React community is constantly growing and already has nearly 140k stars on Github. Having this in mind, we can say that there will never be an insoluble challenge in your project because the internet is full of React JS-related materials uploaded daily. So even if there will be some game-changing update coming, we'll know that in a matter of minutes.

Stable code

React uses a view-model system as the majority of JS technologies does. The significant advantage of React over the competition is the fact that when we change child elements, parent data does not change. It is due to the one-direction downward data flow used in React. Due to this fact, when modifying an object, the developer only needs to make changes and corrections to it, and only this one element will be updated. It improves the stability of the code and the application's performance.

Easy transition to mobile app

Did you know that you can create React app for the web and easily convert it into a mobile app? It is because React code is highly compatible with React Native code. Therefore, if you anticipate your company's growth and there is a chance, someday you will need a mobile app React JS is a way to go! Transitioning from React JS to RN is a much cheaper and faster option than starting an application in a different language from scratch.

Great performance

The performance of web applications built with React is one of its most substantial benefits. React owes this to the virtual DOM. The classic DOM has a tree structure, so changing something at the top can negatively affect the interface. Virtual DOM, on the other hand, is Facebook's answer to this problem. It allows virtual changes to the DOM. It means that before they are introduced into the actual document object model of the application, and before the user sees the changes, the algorithm checks on vDOM where these changes need to be made and how to do it best. Only then are the changes made to the application's DOM. Its guarantees a much better performance and user experience in dynamic web applications with many interactive elements.

Saved Time & Money

Thanks to the fast and relatively cheap development process, applications developed in React Native are an excellent solution for creating, for example, a Minimum Viable Product. What's more, the nature of this framework allows for quick changes in the project, and any mobile app developed in it is highly scalable.

Great User Interface

App appearance is one of the most critical issues if you want to keep the user with you and make him loyal to your app. User interface is responsible for the visual layer of digital products, and React was created to build them. React components not only save resources but are also responsible for making the app UI. Creating a layer that is visible to the user is like arranging a puzzle because the interface consists of many components connected. Developers can use not only rich libraries of previously prepared components but also create their own using JSX. This flexibility allows for the production of beautiful user interfaces in a relatively short time.

Under the hood of React JS, as mentioned earlier, is JavaScript scripting language. It is a text-based language that makes web applications interactive. Compared to other programming languages such as HTML or CSS, which are responsible for static elements like the structure of a web app, JavaScript is responsible for clickable elements that occupy the user. That's why React is an excellent solution for dynamic web applications. React API (Application programming interface) is relatively small, making its use intuitive and straightforward than other technologies. To be more precise, to create user interfaces, React operates on two main APIs - React vDOM and React component API. The previously mentioned React components, which are responsible for building the UI quickly and efficiently, like using Lego blocks, use JSX (JavaScript XML). React vDOM stands for quicker refreshing of pages and better stability.

React component is simply a code element (UI) written in JavaScript that can be reused many times while writing an application. The React team can use ready-made components included in React or build their own depending on the needs.

React JS is a UI library based on JavaScript technology. As can be easily deduced, React is responsible for building and rendering the UI (both server-side rendering and client-side rendering). It is used to create beautiful and responsive UIs for web apps. RN, on the other hand, is the entire framework dedicated to building cross-platform native-like mobile apps. React JS uses Virtual DOM for rendering with more technical differences, while its little brother uses Native APIs. Both of these technologies are connected because React JS is at the heart of RN. To sum up, React JS is a javascript library used for web development, while React Native is a whole framework used to develop mobile apps.

JSX is a React extension that makes modifying the DOM (Document Object Model - a way of representing complex XML and HTML documents in the form of an object model) to add dynamic content faster and easier. The developer can do it using simple HTML-style code mixed with custom tags for the React components. Moreover, this solution works on all browsers and systems. Using syntax called JSX significantly improves website performance and speed of quality development.

Using JSX, React JS creates an in-memory data structure cache - Virtual DOM. The classic DOM using HTML works great for static pages because changing page elements without reloading them is adapted. Still, if the page has a lot of interactive features, there is a problem. That's because the entire DOM has to refresh itself if the user takes action. It lowers the website performance and user experience. The Virtual DOM, a feature of React JS, allows only those sections that have been interacted with to be reloaded. It significantly speeds up loading times and thus provides a great user experience.

Whether you're scrolling through Facebook, Instagram, or looking for an apartment on Airbnb, all of these pages were created using React JS. Likewise, if you do Netflix & chill, you can be sure that the web app you are looking at was made in React. These are just a few of the great companies that trusted it; the list is very long and includes players like Dropbox, Imgur, Reddit, New York Times, etc.

There are many use cases of this user interfaces library. React is an ideal solution when you want to build a web app that will be very dynamic and interactive while also having an excellent and responsive user interface. Still, you can also develop a static app if you want. What's more, its development is relatively fast and economical, making it an ideal choice when building an MVP (Minimum Viable Product). Web applications developed with React can be quite simply transformed into mobile apps using React Native. We have a solution ideally suited to the subsequent scaling of the company and the product.

The initial early prototype of React called "FaxJS" was deployed in 2011. React's original author is Jordan Walke - a software engineer from Facebook. It entered the public domain in 2013 at the JavaScript conference. Another important date is April 18, 2017, because then the old rendering algorithm, Stack, was replaced by React Fiber. Facebook's JavaScript library started with version 0.3.0 in 2013; now, it's in version 17.0.1, released in October 2020. Considering how many updates React has received over the years, we can confidently assume that it will be supported for many more years.

It is a frequently asked question that is already wrong in its assumptions. That's because React is a JavaScript library, not a framework. So what is the difference between library and framework? A framework is a set of predefined rules that developers can use to make an app. It contains the control flow and many white spots where programmers can add their code, making it more complex than a library or other software package. A library is a collection of class definitions that needs to be compiled and integrated into the system. The reason for this, it's code reuse - getting the job done without writing your own tedious, redundant code by using someone else's already registered work. With React, however, you can write your components using JSX. These classes may have been built with specific operations in mind, but they are not limited because anything can be used as long as you access them through an API (Application Programming Interface). They will usually focus on only one piece of functionality and store their data within other libraries or frameworks, which means less redundancy when adding new features!

React JS gained its popularity because Facebook responded to developers' needs. It reduced the need to write large amounts of often repetitive code by using components. Moreover, by using JSX (a unique syntax that allows HTML quotes and HTML tag syntax applications for rendering specific subcomponents), the whole process is faster, components can be built from scratch, and rebuilding an HTML application is much less resource-intensive. Transparency, flexibility, and simplicity are the features that make React the future of web development. The technology that Reacts is written on also significantly impacted its popularity because it is JavaScript. It has been on the market for many years; therefore, the developers didn't have much problem quickly learning the new Facebook technology.
