It was created by Facebook in 2013 and has become one of the most popular libraries in use today.
ReactJs differs from other libraries in that it focuses on the view layer only. This makes it lightweight and efficient, so it is often used to create large applications.
How ReactJs works
When a React component is updated, React determines which components need to be updated and only updates those components. This makes React applications more efficient and prevents unnecessary updates from being made.
The benefits of using ReactJs
React also uses a virtual DOM. When you make changes to a React component, React compares the new version with the old version of the component. It then creates a list of the changes that need to be made to the DOM. This makes your app faster and more efficient.
The drawbacks of using ReactJs
One drawback is that React is not a complete solution. It requires another library, such as React Router or Redux, to fully function. This can add complexity and confusion for developers who are new to React.
Another downside is that React can be slow when used with large applications. This is because React creates a new component for every change, even if the change is minor. So while this approach makes development easier, it can impact performance in production environments.
