first parameter in useQuery

[sshanzel]

Hi!

First of all, thank you very much for this wonderful library. More power to the team and everyone involved in this open-source community.

My question is, what is the use of identifying a key for the first parameter? Though I am aware that it will be the unique identity of the hook itself. Is there any other use for it from the client's perspective? I would like to suggest something but I am still new to this library and wants to make sure of my thought first.

Wish this library all the best!

Thanks!

Best Regards,
Lee
