React is known for its focus on building reusable components, which allows developers to create complex and scalable user interfaces in a more efficient way. React components can be combined to create a complete application, and can be updated efficiently and without affecting application performance.
React is a free and Open Source Frontend Framework.
React uses the virtual DOM to make it easy for developers to build large web applications using data-intensive components that can be reused throughout the application.
The main feature of React is its ability to respond to changes.
React has a few core concepts:
Components are the basic building blocks of your application. You can think of them as functions that return a virtual DOM tree or an actual DOM node (rendered by React). This makes it very easy to modularize your code base into reusable components that can be composed together into more complex ones.
Stateless functional components are basically function-oriented versions of stateful class-based components: they don’t have their own internal state but allow you to pass properties of the parent components through props. They’re great when you want something quick and dirty without the need for state management.
To build an application that works well on multiple platforms and is fast or interactive, the MVVM (Model-View-ViewModel) pattern is useful because it allows you to make changes to models without harming the user’s presentation.
If you are looking for a tool for web application development, you should definitely consider React.
