    • Ans. 

      React DOM updates by comparing the virtual DOM with the actual DOM and only updating the necessary components.

      • React creates a virtual DOM to represent the UI components.

      • Only the necessary components are updated in the actual DOM, minimizing performance impact.

    • Q1. What is prop drilling
    • Ans. 

      Prop drilling is the process of passing props down multiple levels of nested components in React.

      • Function declarations are fully hoisted, meaning they can be called before they are declared.

      • Hoisting can lead to unexpected behavior if not understood properly.
