Can we unmount a component manually?


In this exercise, it explained some ways that a component can be unmounted. However, is there a way to unmount a component manually without having to do something like close the web browser?


Yes, ReactDOM provides a way to remove a component from the DOM through code manually.

You can use the method ReactDOM.unmountComponentAtNode(container), which will remove a mounted React component from the DOM in the specified container, and clean up any of its event handlers and state.
