React Simplest

1. The React Component Types — Class-Based Component and Function Component
2. Before the 16.8 version of React:
   • The class-based type is required if the component will manage the state data and/or lifecycle method (more on this later). Hence, it is called a stateful component.
   • The function component type cannot maintain state and lifecycle logic. And as such, it is referred to as a stateless component.
3. Unidirectional flow
4. This type is the simplest form of React component because it is primarily concerned with how things look.

React Hook

1. Hooks are a new addition in React 16.8. They let you use state and other React features without writing a class.
2. Only Call Hooks at the Top Level
   Don’t call Hooks inside loops, conditions, or nested functions.
3. Only Call Hooks from React Functions
   Don’t call Hooks from regular JavaScript functions.

React Context

1. Solved Props drilling issue without third Party Packages

Redux Sample

Action -> Reducer -> Store -> UI

1. Action: An object describing "what happened"
2. Reducer: An function that takes a current state value and an action object, and returns a new state value.
