Work out detailed guide and explanations on when to use `useState` and when `useQuery`

[269652]

Once we implemented useQuery it replaces useState in some cases.

It's a must have for lists of an indefinite / constantly growing size. If you only have a finite number of states stored in a list then you can still use useState and keep track of your states / ids manually.

useState hasn't been optimized for large datasets. useQuery is generally preferable if you plan to increase the number of states stored in a list constantly over time.

This involves

• Writing a medium post
• Adding detailed documentation
• Asking stackoverflow questions

All this can be done by anyone who sufficiently understands react server and the two different approaches of storing and querying data.
