Using React JS, developers can build interactive web apps. The framework works by monitoring component state using a virtual DOM. When a component changes, it refreshes only the parts of the page that need it. React can be used in new applications or can be integrated into existing web apps.

The main goal of React is to speed up the development process. It also keeps track of the changes made to data over time. This is a key advantage over other implementations.

Unlike other frameworks, React works with an abstract copy of the Real DOM. The DOM is updated minimally, which increases the speed of re-rendering.

To keep the components in sync, React uses props. Props are JavaScript data objects like strings, arrays, and functions. They can be used to pass data between components or to keep children components in sync.

Functional components are the most commonly used components in React apps. These components allow data to be passed directly between components without the need for callbacks. They also have hooks to minimize expensive data calculations.

A common issue with React is the need to update DOM. Most frameworks update the DOM unintelligently. For example, when a component is changed, the DOM is reloaded to reflect the new data state. React’s use of a virtual DOM reduces re-render time by comparing the new DOM with the old one.

React is also known for its asynchronous rendering. This makes it possible for developers to update the state data without causing unnecessary re-renders.
