Web development has grown enormously. The technology for developing front-end web apps has evolved almost every day. The new tools, frameworks, and libraries have overtaken the ideal approach of HTML, CSS, and Javascript. Different frameworks and libraries made web applications more efficient and dynamic.
There are many multiple frameworks options available like Angular, Node, Vue.js, and more. But ReactJS is one of the most advanced, easy-to-use, and popular frameworks capable of rendering front-end web apps that are dynamic, speedy, highly responsive, and scalable. It is a free, open-source front-end javascript library used to build highly responsive user interfaces based on UI components. Developed by Jorden Walke, a software engineer at Meta (Facebook), he aims to create a javascript library to simplify the development process and ease a more comfortable user experience.
According to a survey by Stack Overflow, ReactJS ranks number one among the other frameworks in terms of popularity and user experience. More than 2,00,000 websites in the world that uses React like Netflix, Facebook, Instagram, Dropbox, BBC, Tesla, and more. The popular framework uses one of the key features that you must consider for the development, Explore Top 5 best Features of Reactjs below,
Essential Features of ReactJS
1. Virtual Dom
React contains lightweight representations of original DOM (Document Object Model) in its memory called Virtual DOM. Virtual DOM is one of the most key characteristics facilitating the fast, scalable, and flexible development process.
Updating an entire DOM is much slower than many javascript operations. Most of the JS frameworks update DOM as a whole. That’s the reason that makes it slower. But when an update is required, React updates only Virtual DOM and compares with the original DOM. Suppose any difference is found between virtual and original one, then original DOM update by only that particular portion of the difference. This feature makes React faster compared to the other frameworks.
2. JSX
JSX stands for JavaScript XML. JSX makes writing React components and the building blocks of UI easier as it provides syntax almost identical to HTML. JSX makes the code easier and debug. JSX also helps the developers avoid using complex javascript DOM structures. Check below the code that represents how JSX embeds HTML into JavaScript code.

const ele = <h1>Welcome to {name}</h1>;
3. One-Way Data flow
As the name suggests, React supports one-way data flow or unidirectional data flow, which means developers have to use a callback function to edit components to prevent them from editing directly. Flux manages the one-way data flow. Flux is a javascript library that provides flexibility and boosts the efficiency of the application. One-way data binding is one of the most important Features of Reactjs as it allows for full control over the application.
4. React Native
It is a framework based on ReactJS that uses native components instead of web components. Like ReactJS, React Native has its own components as the developer has to study how react-native components are working. In addition, it can transform the react code to make it compatible with iOS and Android platforms.
5. Declarative UI
ReactJS is the best framework for developing effective and interactive user interfaces in both web and mobile apps. Create simple views for every state in your application and react will update just the right components when data changes.
Final Words
That’s it! We are done from our side, and We hope that you understood the content related to the core features of ReactJS. The framework is literally in demand because of its wonderful, developer-friendly, and easy-to-use features to build efficient Reactjs-based applications.
Many tech companies use the ReactJS framework to build a user-friendly front-end web and mobile application. Above mentioned features are one of the most important, and each plays a significant role in providing quality front-end solutions.
