Functional Components vs Class Components

Functional components in React Native are JavaScript functions that render a React element. They can accept a single argument which is an object containing component properties.

Class Components in React Native are ES6 Classes that extend from a base class.

Functional components	Class Components
Like normal JavaScript functions, Functional components can be defined using the arrow function or the function keyword.	A class component is an class that extends from React base class. It requires a render() method.
Class components initialize a state in its constructor.	Functional components make use of the useState hook
A functional component is just a plain JavaScript pure function.	Class Component create a render function which returns a element
Hooks can be easily used in functional components to make them Stateful.	It requires different syntax inside a class component.
Constructors are not used.	Constructor are used as it needs to store state.
Syntax :  function Welcome() {  return  Hello, Aman; }	Syntax :  class Welcome extends React.Component { render() {  return Hello, Aman;  } }
