Mega Web Development Bootcamp with React Bootstrap 5, Redux, and REST API - Props Versus Context API

The video tutorial covers the use of imports and hooks in a React app, focusing on the useEffect, createContext, useReducer, and useContext hooks. It explains the concept of context and props for passing data between parent and child components, highlighting the limitations of props. The tutorial demonstrates how to troubleshoot common errors, such as infinite loops, and introduces the context API as a more efficient way to manage global state across components.

Which of the following hooks is NOT mentioned as being imported in the app JS file?

• createContext

• useEffect

• useState

• useReducer

What is a limitation of using props to pass data from parent to child components?

• Props are not supported in React

• Props cannot be used with functional components

• Props can only pass numbers

• Props require passing data through every level of the component tree

What issue was encountered that led to the application not running?

• Incorrect import statements

• Incorrect use of CSS

• Too many re-renders causing an infinite loop

• Missing component files

What was identified as the cause of the infinite loop error?

• Directly setting a value without a function

• Incorrect use of the useEffect hook

• Using props instead of state

• Missing return statement in a component

How does the context API improve data management in React applications?

• By allowing data to be passed directly to any component without props

• By eliminating the need for state management

• By automatically updating all components on data change

• By providing a built-in database for React applications

What is the purpose of the useContext hook?

• To use the created context in components

• To create a new context

• To handle component errors

• To manage component lifecycle

What happens to the props when the context API is used?

• Props are only used for styling

• Props are duplicated across components

• Props are no longer needed for passing data

• Props are automatically converted to state
