- Q2. What is JSX in react js?
- Ans.
JSX is a syntax extension for JavaScript used in React to write HTML-like code within JavaScript.
JSX allows developers to write HTML elements and components in a syntax similar to HTML.

JSX expressions must have a single parent element to be rendered properly.

Some difficulties faced during assignments include unclear requirements, tight deadlines, technical challenges, and communication issues.
Unclear requirements can lead to misunderstandings and delays in completing the assignment.

- Q4. What are react hooks? Explain any 5 or explain hooks which you used in your assignment
- Ans.
React hooks are functions that let you use state and other React features without writing a class.
useState() - allows functional components to have local state
useEffect() - performs side effects in function components
useContext() - allows you to subscribe to React context without introducing nesting
useReducer() - an alternative to useState for more complex state logic
useMemo() - memoizes the result of a function
- Q5. What is HOC in react js?
- Ans.
HOC stands for Higher Order Component in React.js.
HOC is a pattern where a function takes a component and returns a new component with additional props or functionality.
It is used for code reusability, logic abstraction, and separating concerns.
Example: WithAuthentication HOC can add authentication logic to a component.
