Why should you use React in 2019?
By Iryna Savruk /

React has been widely adopted and belongs to the most popular and promising frameworks among front-end developers.

React is a library for creating user interfaces for large web applications and allows processing data without frequent page reloadings. It is used for reliable and intensive programming. This framework is a perfect choice when you have lots of dynamic content in the application.

Decreased development time

React.js helps to build reusable UI components, that decrease the development time. While updating one component on the page, React modifies only specific part of it and you don’t have to refresh the website completely.

Also, React constantly introduces API improvements, including better support for code splitting and concurrent rendering. Recently, new React hooks API has replaced the class API, which also enhanced the performance.

Support of HTML

React is a JavaScript based library product which also supports HTML language. It allows a developer to use HTML code and render subcomponents with HTML tags and syntax.

JSX Usage

To improve the performance, React uses JSX, a syntax extension to JavaScript. Even though React doesn’t require it, most developers use it as a visual aid when working with UI inside the JavaScript code. In addition, JSX allows React to show more error and warning messages.

The benefits of Virtual DOM

Virtual Document Object Model (DOM) of React renders faster and works more efficiently regardless of which browser you use. Its virtual DOM is one of its best features, even though its learning curve is relatively low. The DOM is the representation of the web page to the browser. React has its own virtual DOM that manipulates the actual DOM of the browser. Due to the fact that React’s DOM is much faster than the browser’s one, it improves the performance significantly.

Virtual DOM also helps developers manage an extensive database. Prompt rendering feature considerably lessens the amount of DOM operation and speeds up the updating process. React works well for both server-side and client-side rendering. It helps to build dynamic and supporting MVC programming structure.

Major Browsers Support

React is very popular among browsers. They optimize their engines as soon as a new version of React appears. For example, when React introduced Hooks, Chrome optimized the V8 engine straight away. Mozilla also used React to build the Firefox DevTools UI and debugger. The React creators are thrilled to cooperate with major browsers and will continue working with “user interface responsiveness, display locking, main thread scheduling, and other initiatives like virtual scrolling APIs” according to Dan Abramov.

Adoption by large companies

React is created and maintained by Facebook. Since 2009, when it was released, React was adopted by many other companies like Instagram, Airbnb, Uber, WordPress, Dropbox, PayPal, Netflix, Yahoo, Walmart, and others. Since React is supported by major companies, we can predict that it will gain even more popularity in the coming years.

Active community of contributors

React community supports a wide number of open source projects. React developed a specific ecosystem of open source libraries, components, and tools including such projects as React Native, Framer X, and Gatsby. React Native has the same technical basis as React itself, which is used for mobile apps development for iOS and Android with only one set of source code. At Incora, we have a significant experience in developing applications with the help of both React and React Native.
