This project demonstrates three levels of React state management using the useState hook, along with Tailwind CSS for styling.
We go from a simple counter → medium form example → hard nested array update example.
In React, state is a built-in object that stores dynamic data for a component.
When state changes, React automatically re-renders the component to reflect the updated values.
We use the useState hook to:
- Store values
- Update values
- Trigger re-renders
Syntax:
const [stateVariable, setStateVariable] = useState(initialValue);
