In React, state refers to an object that holds data or information about the component. State is managed within the component (just like variables declared in a function). However, unlike regular variables, when state changes, React re-renders the component to reflect these changes, keeping the user interface in sync with the data.
A Hook is a special function that lets you “hook into” React features. For example, useState is a Hook that lets you add React state to function components.
