react-dom vs react-router-dom: What are the differences?

Key Differences between react-dom and react-router-dom

React-dom:

1. Render DOM elements: React-dom is a package that provides methods for rendering React components into the DOM. It includes methods like ReactDOM.render() which takes a React element and mounts it into a container DOM node.

2. Handles application lifecycle methods: React-dom provides methods for handling application lifecycle methods like componentDidMount(), componentDidUpdate(), and componentWillUnmount(). These methods allow developers to perform certain actions at different phases of a component's lifecycle.

3. Updates and re-renders DOM efficiently: React-dom efficiently updates and re-renders the DOM by comparing the previous and current virtual DOM representations. It only updates the specific parts of the DOM that have changed, providing better performance compared to traditional HTML manipulation.

React-router-dom:

1. Handles routing in a React application: React-router-dom is a package that provides routing capabilities for a React application. It allows developers to define different routes, navigate between them, and render different components based on the current URL.

2. Supports different types of routing: React-router-dom supports different types of routing, such as client-side routing and server-side rendering. It provides components like BrowserRouter and HashRouter that handle different types of routing methods.

3. Enables URL parameter handling: React-router-dom enables handling of URL parameters, allowing developers to pass dynamic values through the URL and extract them in the components using Route and Link components.

In Summary, react-dom is mainly responsible for rendering React components into the DOM and handling lifecycle methods, while react-router-dom provides routing capabilities and supports different types of routing methods in a React application.
