React Hooks Classes It is used in functional components of React. It is used in class-based components of React. It will not require a declaration of any kind of constructor. It is necessary to declare the constructor inside the class component. It does not require the use of this keyword in state declaration or modification.Keyword this will be used in state declaration (this.state) and in modification (this.setState()).It is easier to use because of the useState functionality.No specific function is available for helping us to access the state and its corresponding setState variable. React Hooks can be helpful in implementing Redux and context API. Because of the long setup of state declarations, class states are generally not preferred.
