hello i have a problem
I created a useState called [users, setusers]
and in useeffect, I have assigned a delete function for each user.
this delete function needs to reach users state
But the problem starts here. When I want to reach users through the delete function,
I get the initial state of the state, (the state at the time I created the first user object)

You can get the latest value by passing a function to
setUsers
and it will be passed the current value as a parameter. See reactjs.org/docs/hooks-reference.h...can you look at this,codesandbox.io/s/the-appropriate-u...
what is the reason of this
Because of a stale closure, following the rules of Javascript closures and scope. dmitripavlutin.com/react-hooks-sta...
