- Virtual DOM:
To address this problem, React JS introduced the concept of Virtual DOM. When changes are made in the DOM, React JS creates a copy, known as the Virtual DOM. This copy is then compared with the actual DOM, and only the differing elements are re-rendered. As a result, this approach reduces computing power requirements and loading times, leading to improved performance.
- React Native:
One of the remarkable aspects of using React JS is its close integration with React Native, a technology used to develop front-ends for mobile applications. React Native provides a rich library of pre-built components for both iOS and Android platforms. By mastering and employing React JS, developers can easily transition to React Native and create native mobile applications.
