What is component
In programming, a component is a modular, reusable, and self-contained part of a software system. It performs a specific function and can interact with other components through well-defined interface.
In React, there are primarily two types of components:
Functional Components :
These are simple JavaScript functions that return JSX (JavaScript XML). They do not have their own state or lifecycle methods but can use hooks like useState and useEffect to manage state and side effects.
Class Components :
These are ES6 classes that extend from React.Component. They have their own state and lifecycle methods like componentDidMount, componentDidUpdate, and componentWillUnmount.
