What are the new hooks introduced in React 18?
React 18 introduced several new hooks, including useTransition
, useDeferredValue
, and useId

Can you explain how useTransition
works?

allows you to mark updates as non-urgent. It helps in managing state updates that can be deferred, improving user experience during heavy rendering.

?
useDeferredValue
