Explain how data is recognized from child to parent

I didn't understand the explanation in the video. Can you explain this in a different way?

Hi Rachel Heneault, in React the expression "lifting state" is where / how you can uplift state that may be passed down through props to child components, which is achieved by passing a function/handler as a prop to the child component that is triggered via an event the user makes (e.g. a click event), which will then therefore update the value in state sending it back to the component that state is defined in (Usually your top level entry App component in most cases).

For more information, please check out the official React documentation

this is so confusing. the way props are passed is making it so confusing for me. i understand props though. i guess the modules are making it confusing, by navigating through them.

i wish there can be several examples to explain a particular idea.
