What is the primary purpose of React Routing?

  1. Managing state in React applications

  2. Handling user input and events

  3. Enabling navigation between different pages or components in a React application

  4. Optimizing the performance of React applications


Correct Option: C
Explanation:

React Routing is a library that allows you to create single-page applications in React, where the entire application is loaded on a single page and navigation between different views or components is handled through client-side routing.

Which of the following is a core component of React Routing?

  1. Router

  2. Route

  3. Switch

  4. Link


Correct Option: A
Explanation:

The `` component is the core component of React Routing. It wraps the entire application and provides the necessary context for routing to work.

What is the purpose of the `` component in React Routing?

  1. Defining the path for a specific route

  2. Rendering the content for a specific route

  3. Handling user interactions on a specific route

  4. Managing the state of a specific route


Correct Option: A
Explanation:

The `` component defines the path for a specific route in React Routing. It specifies the URL pattern that should match for the route to be active.

What is the difference between the and components in React Routing?

  1. is used to define multiple routes, while is used to define a single route

  2. is used to handle user interactions, while is used to render content

  3. is used to manage the state of a route, while is used to define the path for a route

  4. is used to optimize the performance of a route, while is used to define the layout of a route


Correct Option: A
Explanation:

The `` component is used to define multiple routes in React Routing. It ensures that only one route is active at a time, preventing multiple routes from rendering simultaneously.

Which of the following is used to navigate between routes in React Routing?

  1. `` component

  2. `` component

  3. `` component

  4. `` component


Correct Option: A
Explanation:

The `` component is used to navigate between routes in React Routing. It provides a way to link to other routes within the application, allowing users to navigate between different views or components.

What is the purpose of the exact prop in the `` component?

  1. It ensures that the route is only active when the URL matches the path exactly

  2. It prevents the route from being active when the URL matches the path partially

  3. It optimizes the performance of the route by caching the rendered content

  4. It manages the state of the route by keeping track of the active path


Correct Option: A
Explanation:

The exact prop in the `` component ensures that the route is only active when the URL matches the path exactly. This is useful when you want to prevent a route from being active when the URL matches the path partially.

What is the difference between the history and hash modes in React Router?

  1. History mode uses the browser's history API, while hash mode uses the URL hash

  2. History mode is more secure than hash mode

  3. Hash mode is more SEO-friendly than history mode

  4. History mode is supported by all browsers, while hash mode is not


Correct Option: A
Explanation:

History mode in React Router uses the browser's history API to manage the URL, while hash mode uses the URL hash to manage the URL. History mode is more secure and SEO-friendly than hash mode, but it requires server-side configuration to work properly.

What is the purpose of the useParams() hook in React Router?

  1. It allows you to access the parameters of the current route

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The useParams() hook in React Router allows you to access the parameters of the current route. This is useful when you need to access dynamic values from the URL, such as the ID of a post or the name of a category.

What is the purpose of the useLocation() hook in React Router?

  1. It allows you to access the current location object

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The useLocation() hook in React Router allows you to access the current location object. This is useful when you need to access information about the current URL, such as the pathname, search parameters, and hash.

What is the purpose of the useHistory() hook in React Router?

  1. It allows you to navigate between routes

  2. It allows you to access the current location object

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The useHistory() hook in React Router allows you to navigate between routes. This is useful when you need to programmatically navigate to a different route, such as when a user clicks a button or submits a form.

What is the purpose of the withRouter() higher-order component in React Router?

  1. It allows you to access the routing context in a component

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The withRouter() higher-order component in React Router allows you to access the routing context in a component. This is useful when you need to access information about the current route, such as the pathname, search parameters, and hash, in a component that is not a direct descendant of the `` component.

What is the purpose of the Redirect component in React Router?

  1. It allows you to redirect users to a different route

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The Redirect component in React Router allows you to redirect users to a different route. This is useful when you need to redirect users to a different page after they have completed a certain action, such as logging in or submitting a form.

What is the purpose of the Switch component in React Router?

  1. It ensures that only one route is active at a time

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The Switch component in React Router ensures that only one route is active at a time. This is useful when you have multiple routes that can match the same URL pattern, and you want to ensure that only one of them is rendered.

What is the purpose of the Route component in React Router?

  1. It defines a route and its corresponding component

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The Route component in React Router defines a route and its corresponding component. It specifies the URL pattern that should match for the route to be active, and the component that should be rendered when the route is active.

What is the purpose of the Link component in React Router?

  1. It allows you to create links to other routes

  2. It allows you to navigate between routes

  3. It allows you to manage the state of the current route

  4. It allows you to optimize the performance of the current route


Correct Option: A
Explanation:

The Link component in React Router allows you to create links to other routes. This is useful when you want to allow users to navigate between different views or components in your application.
