I have a Small Query, I tried to google it but couldn't find the solution.

When a React Component state is changed(useState()), so the whole page is rendered or that specific React Component is rendered like in Ajax?

CodePudding user response：

Only the component will be rendered again.

CodePudding user response：

The useState will render all the components associated with it, meaning if you put the useState in the parent component it will also re-render the children component.

CodePudding user response：

When State changes in the child component do not affect the parent component, but when a parent component's state changes, all child components are rendered.
