ReactJS is the most reliable JavaScript-based library for creating seamless mobile and web applications. Developers use this programming language to render front-end web applications to make them fast and scalable. Furthermore, it also helps fine-tune the app’s user interface.
ReactJS is in high demand globally as the number of websites and mobile apps increases daily. Java is one of India’s most popular programming languages, and the country has a vast pool of coding talent. As a result, the world is turning to the southeast Asian country to .
The following sections discuss the features of ReactJS and why businesses prefer it over other JavaScript libraries.
The 10 Best Features of ReactJS
Declarative UI
ReactJS can create interactive and dynamic UI for mobile apps and websites, which stands out as one of its most noteworthy features. Consequently, ReactJS codes are more user-friendly, easy to debug, and readable. The built-in library can be used to create a seamless view system for every state in the app, while ReactJS’s framework corrects the components whenever the data changes. To suffice, ReactJS helps simplify the app-building process for developers.
Virtual DOM (Document Object Model)
Virtual DOM assists developers in building scalable apps and websites using ReactJS. It also helps improve the speed of the development process and acts as unidirectional data binding. When a developer makes changes in the app, the modification is first rendered in the Virtual DOM, then a comparison between the original and modified versions is available for review. The changes are made only in the relevant areas in the DOM, while the rest remains the same. This helps in hastening the development by using low memory.
Component-Based Architecture
ReactJS is entirely component-based, which means that its library breaks an application into various components. Each component has a specific design and logo programmed in JavaScript, and developers can make as many changes as they require without editing the code. ReactJS is incredibly easy to use due to this feature.
JSX
ReactJS uses JSX codes, a combination of JavaScript and HTML that helps define the UI elements in a mobile or web application. JSX has a syntax similar to HTML, allowing ReactJS developers to code in JavaScript and HTML structure in a single file. The code is very easy to read and a convenient way to create any application.
Event Handling
ReactJS can create its own event system fully compatible with the W3C object model. All browser-native events include Synthetic Event, which gives a cross-browser interface to a native event. Hence, developers do not need to worry about incompatible event names and fields. Furthermore, the ReactJS event system is implemented via event delegation and has a large collection of event objects to reduce memory overhead.
Data Binding
ReactJS has a unidirectional data binding mechanism, meaning that data only flows in one direction in the library -from the parent to child components. Binding is the way properties in the library are communicated to the components. This feature prevents developers from modifying any components, as they can simply edit them by using the callback feature. This hassle-free process makes ReactJS a modular and simplified framework.
Pre-configured UI Components
ReactJS has an open-source developer community. Hence, developers can find codes in ReactJS that can be used in other applications. The library is full of numerous pre-configured user interface components that assist developers in building interactive applications.
Stability
ReactJs has a stable core that enables a smooth downward data flow. Developers can make any modifications to the child structure, and the parent structure will remain unaffected. Furthermore, the developer can change any state, alter any object and proceed with the update without worrying about the elements which were unchanged. ReactJS’s structure ensures the code is always stable and executes smoothly.
Performance
ReactJS uses an architecture called Flux controls that lets the developer control the application workflow and enhance the user experience as required. Furthermore, with the complex UIs divided into various elements and a Virtual DOM ready to render any changes without impacting the original code, ReactJS is hands-down a high-performance framework.
Server-side Rendering
ReactJS was introduced as a language that enhances the page loading time and does not depend on the delivery of the components. It allows the browser to render the page without waiting for the JavaScript codes to be stacked and executed. ReactJS allows pre-rending the underlying states of the components only on the server side; hence the page loads faster.
Popular Apps Built Using ReactJS
- Facebook (Meta)
Facebook was one of the first applications to be built using ReactJS. Facebook’s mobile app was built with React Native and was the place to create the ReactJS library. The website of the social media platform was built completely via React.
- Dropbox
Dropbox is a cloud-based storage service that empowers its users to save media and data on the cloud and share it across networks.
Instagram is one of the most well-known photo and video-sharing platforms, with an enormous user base. The app’s features, such as Google Maps APIs, search engine accuracy, geolocations, and hashtags, are all designed using the ReactJS library.
- GitHub
GitHub is one of the largest software development platforms, with a gigantic community of developers across the globe. Interestingly, its founders chose ReactJS for building their web application, owing to its flexibility and ease of use.
Another part of Meta’s conglomerate of social apps, Whatsapp’s UI, is also built using ReactJS. After Facebook bought the application, it refined the messenger for upcoming features using ReactJS.
- BBC
BBC is a media industry pioneer, providing hard-hitting journalism to its global audience. It migrated its website to ReactJS in 2015 and recently launched its single-page application, “Simorgh,” based on the framework.
- Codecademy
Codeacademy is a popular freemium online platform that educates users on programming languages. The platform has numerous hours of study materials and streaming videos, and the credit for its scalability goes to ReactJS.
Final Thoughts
ReactJS is a progressive technology that enables high-performance presentation on any mobile and web application. Developers can rely on its extensive library for building various kinds of projects. The aforementioned features highlight ReactJS’ future-proof identity and the usefulness of the JavaScript framework.
Like many popular brands, businesses should look at ReactJS when they think of developing mobile and web apps that can be scaled easily and perform seamlessly. Also, businesses can maximize their development output by .
