The state object is a built-in React object that holds data or information about the component. The state of a component can change over time, and when it does, the component re-renders.
It has been established via a lot of trial and error, pilot programmes, and personal observation that React Native apps can be arranged into five types of states. Each sort of state has its own set of laws and interacts with the others in a certain way.
React uses a simple JavaScript object called state to encapsulate information about the current state of a component. It's taken care of by the component (just like any variable declared in a function).
A component's state should persist throughout its existence, thus we must first establish an initial state, which we should do in the function Object() { [native code] } of the component's class.
State should never be explicitly modified.
The useState hook is most commonly used in React to maintain local state. Local state would be required, for example, to show or hide a modal component or to track values for a form component, such as form submission, when the form is disabled, and the values of a form's inputs when the form is disabled.
