You’ll often hear the term Single Page Application (SPA) when people talk about React. It’s the idea of bundling a site’s structure, text, and core functionality and sending it to the user in one small package. This makes the site feel much faster and more responsive.
Without those jarring waits between clicking a link and the next page loading, your site feels more like a fast desktop application than a traditional website.
In a business environment, React, and other SPA libraries are great when you need fast data entry, “offline” capabilities for when a user is on the road, or even to mimic the look and feel of a “native” office tool or mobile app. It’s also likely that you’ve already used one — Google Maps, Twitter, and Facebook are all well-known examples of SPAs.
When Facebook started using React, they thought it was so impressive that they decided to share it with the world. When they released the Open-Source library, hundreds of businesses started adopting it, due to its appeal to developers and the end-users:
Reusable components – React operates on a component-based structure. Each component acts as a building block and can be reused multiple times across the app. This helps give a consistent look and feel to the app and makes maintaining the codebase faster and easier.
Fast render – The use of virtual DOMs explains why React apps are so performant. Virtual DOMs are kept in memory. Whenever there are any changes to the view, these changes first apply to the virtual DOM. Then, the updates are applied to the DOM while ensuring a minimum amount of read/write time.
Both React and React Native is widely used with the difference that React JS is designed for web development projects while React Native is used for mobile app development.
