使用钩子更新 object state

Question

I have a question about changing the value of a property within an object using Hooks, How do I do that?

const [user, setUser] = useState({id: '', name: '', email: '', entries: 0, joined: ''})
let count = 5;

And I would like to update the value of the property"entries" with a variable "count".

How do I do that with setUser?

Thanks

This should work;

setUser({
  ...user,
  entries: count
});
