What is React JS and Why it is Used?

React JS is an open-source JavaScript library used for building user interfaces for web applications. It was developed by Facebook and is now maintained by a community of developers. Here is why it is extremely popular and most used technology right now.

React is used for building large and complex applications, where the user interface needs to be updated frequently and in response to user input. It enables developers to build reusable UI components, which can be composed to create complex user interfaces.

React uses a declarative approach to programming, where developers describe what the user interface should look like and how it should behave, rather than manually manipulating the DOM (Document Object Model). This makes it easier to reason about the application’s state and behavior and reduces the likelihood of bugs and performance issues.

React also provides a number of performance optimizations, such as a Virtual DOM (Document Object Model) implementation, which helps to minimize the number of updates to the actual DOM and improve the overall performance of the application.

Overall, React is a popular choice for building modern web applications because it offers a powerful and flexible set of tools for building complex and dynamic user interfaces. Its declarative approach to programming, reusable UI components, and performance optimizations make it a popular choice for developers who want to build high-quality, responsive web applications.
