A React Functional Component is a simple JavaScript function that returns JSX, defining a part of the user interface. It is the most commonly used type of component in modern React due to its simplicity and performance benefits.

Key Features:

• Stateless or Stateful: Can use state and lifecycle features through React Hooks.
• Lightweight: Easier to write and test compared to class components.
• Performance: Executes faster as it avoids the overhead of class-based methods.

Functional components are the standard approach in React for creating reusable and maintainable UI components.
