components

After filling out the form, one clicks a button (on the modal ) and it validates the form data and posts it through a REST API.

What would be the correct way to structure these components in terms of props

My question: How can I use the functions living inside the parent component to change state while the user is interacting with form

Right? Any idea why this would happen? 回答1: Since your condition is falsy and so doesn
