React is a declarative, flexible, and open-source library for building user interfaces based on UI components. It's typically used to develop web applications that require constant data changes on their UIs.
A typical approach would require us to reload the entire website when we click on any component, but React avoids reprocessing every line of code using components. Think of Facebook, where we scroll through the application to see new posts while other page components stay the same.
React is quickly gaining popularity as the best JavaScript framework among web developers.
The following are the critical features of React:
A virtual DOM object is a DOM object representation that creates a virtual copy of the original DOM object. The entire UI is re-rendered in the virtual DOM representation when the web application is changed. The old DOM representation is then compared to the new DOM representation.
Following that, the actual DOM will only update the changed elements. This React feature facilitates and speeds up the application development process.
Everything in React is treated as a component. This means that the development of a web interface or application in React is made up of several components. These components are reusable, which in turn helps in code maintenance when working on larger projects.
This markup syntax describes how the application's user interface will appear. Developers use it to create React components, making the syntax similar to HTML. JSX is one of the best features of React as it makes it extremely simple for developers to write the building blocks.
React uses a unidirectional data flow, forcing developers to edit components via the callback feature rather than directly editing them. The Flux JS application's architecture component aids in the unidirectional flow of data. This increases the application's flexibility, which leads to increased efficiency.
The declarative user interface is the ability to create a dynamic and interactive user interface for websites and mobile applications. This feature makes React code more readable and user-friendly, especially for bug fixes.
Because React JS can create engaging UIs, it also creates an easy-to-use viewing system for each state in an application making the code more predictable and easier to debug.
React supports additional features like routing, API interaction, and state management. It is the best choice when it comes to rendering data.
This framework offers benefits to both developers as well as business owners. It's no surprise that this framework gained popularity quickly and is still on the rise.
