## 1. What is BrowserRouter in React Router?

**Answer**

BrowserRouter uses the browser's History API to create clean URLs without hash. Unlike HashRouter which adds a # in the URL, BrowserRouter provides a better user experience and SEO. However, it requires server configuration to properly handle routes in production.

## 2. Which component should be used to define a route in React Router?

**Answer**

The Route component defines a match between a URL path and a component to display. It must be placed inside a Routes component to work correctly. Each Route specifies a path and an element to render when the URL matches.

## 3. What is the purpose of the Link component in React Router?

**Answer**

Link creates navigation links without reloading the page. Unlike the native HTML <a> tag, Link intercepts clicks and uses the History API to change the URL. This preserves application state and provides faster, smoother navigation.
