#1Implement useAsyncStorage Hook
Medium
react
hooks
state-management
Create a custom React Hook named useAsyncStorage that manages persistent state for a specified key and initial value. The hook should return an array containing the current value and a function to update it, ensuring the state is persisted using async storage.

#2Implement a Retry Function for API Calls
Medium
api
promises
error-handling
Write a function that attempts to call an API and returns a promise. The function should retry the API call a defined number of times if it fails, ensuring there are suitable delays between retries.
