useDefault
A custom React hook that manages a stateful value with a default fallback.
useDefault is a helpful custom React hook designed to manage stateful values with a default fallback when the value is set to null or undefined.
This hook is particularly useful when you need to maintain state values that might be reset or cleared, but should fall back to a predefined default rather than being null or undefined.
