问题 I have a form that uses fetch() to AJAX with a route on NodeJS. When the AJAX POST hits the route, req.body shows an empty object {}.

问题 In the code below I was expecting that inside the useEffect hook console.log procedure will log the list of the tickets fetched by getAllTickets function because list of the tickets is returned without error.However console.log results in logging an empty array that I set up in the state initially.

I have read some people say never to
