What is the use of useContext?

This question is asked by the interviewer to assess your data sharing capability across deeply nested components without prop-drilling.

Sample Answer:

This hook (useContext) allows to consume values from React Context directly in a functional component.

const value = useContext(TestContext);

This useContext helps to avoid passing props manually to each level of the component tree. General use cases wherein the useContext is used are like User Authentication, Theme Switching, etc.
