In today´s technological age, the popularity of React JS has continued to rise and we're here to explain why. Facebook released and popularized the React JS open source JavaScript library in the market. It allows you to work on specific components rather than the entire program, ensuring the fastest possible rendering speed of your application.

Due to its greater flexibility and accessibility, React JS has been expanding as the future of web development.
React JS's ability to employ reusable components allows designers to display data without having to refresh the page after each data-add action, and this feature has given developers the ability to create modern rich user interfaces.
Software engineers use React to build user interfaces because it's a declarative, efficient, and responsive JavaScript library. It is also known as React.js and React JS.

React is the result of significant business investment, which sets it apart from its competitors. React was built by Facebook in 2011, but wasn't open sourced until May 2013, when a GitHub repository was developed and the availability of the library was formally announced.

After being heavily used to build the Facebook and Instagram UI, as well as being tested and reviewed in the wild by other programmers, React started to gain popularity in 2014.
React was created in response to problems commonly faced when developing JavaScript applications. As the size and complexity of applications increased, these problems became more and more annoying. React was built by Facebook and is heavily used by them to solve their difficulties to the quality and efficiency of the library by dealing with comparable problems on other platforms.

Beneficial features of React JS:

● Very efficient: React JSis unique as it has its own virtual Document Object Model (DOM) that houses all its components. This React JS feature helps developers achieve exceptional performance results by being able to calculate what DOM changes are required on real time and update DOM trees accordingly. As a result, React JS avoids costly DOM operations and manages DOM changes effectively and cost-effectively. JSX syntax is another feature that improves the productivity of React JS applications. This is a hybrid of JavaScript and HTML that simplifies the creation of website components by allowing them to work without the need to concatenate strings.

● Extremely fast: Keeping in mind that React JS allows web designers to use the same code sequence on both client / server sides, this helps speed up the development process. The software application will not be harmed by the reuse of application components during the development stage. Another way to speed up the design process is to hire many developers, each of whom will be responsible for their own application development features and components. The program logic will not be affected by this application development procedure.

ReactJS packages are small and quick to download, so developers don't have to take a lot of time installing them. Due to the high quality of code splitting, it is no longer necessary to load the entire program each time. This drastically reduces the time it takes for web applications to load. A faster website load time indicates that the user experience (UX) will be considerably smoother and faster. A UI/UX design agency can also be hired to help guide this process.

● SEO friendly: Except for React JS, most of the JavaScript frameworks on the market are not SEO friendly, which presents a major problem for these frameworks. The SEO friendliness of the React JS library makes it a unique and popular platform as it allows developers to retrieve the virtual DOM that is displayed as a conventional web page.

● Very flexible: React's design allows front-end code to be bundled into custom components, laying a solid foundation for optimization of the entire development process. The React library maintains a stable position: it neither locks you in nor leads you into its way of doing things. For one thing, it specifies how reusable components should be created.

On the other hand, it gives you complete control over how you manage routing and testing, as well as how you structure dependencies and more. This level of flexibility can be disconcerting for beginners, but working in a React development environment is a real joy for experienced developers.
