Q1. What is the importance of key in react, explain in detail.
Ans. 
Keys in React are important for efficient rendering and maintaining component state.
• Keys help React identify which items have changed, are added, or are removed in a list of components.

• Using keys correctly can improve performance by reducing unnecessary re-renders.

• Keys should be unique among siblings but can be reused across different lists.

• Example:

  {items.map(item =>
  • {item.name}
  )}
