React state
State is a built-in object in React that is used to hold information about components. It is what is responsible for the interactivity of components. In the React application, state changes. When there is a change in the component state, React re-renders the component.
This change also impacts how the component behaves and renders on the screen. There are factors that can make the state change – for instance, a response to a user’s action or system-generated events. Props and state are twin features of React. While props essentially pass information from a parent component to a child component, state alters components’ internal data.
Let’s take a look at a search use case for the implementation of state in components. Anytime a user types something into an HTML search input field, the user intends to see this typed information, which represents a new state, displayed somewhere else in the application.
