Retry-Operation function

Summary: A function that automatically retries if it fails.

●While writing programs, we often need functionality that retries code when it fails for any reason.

●For example, suppose we are developing a program that calls an API, and the API request fails due to a "Too Many Requests" error. In that case, we want it to retry so that the chances of receiving the expected response increase.

●For that purpose, this function is created.

❖ Use:

Copy

❖ Arguments:

1. operation: A function that you want to retry in case of failure.
2. retries: Determines the maximum number of times you want to retry.
3. delayMs: Time between two requests, in milliseconds.
4. delayFromFirstAttempt: Determines whether to wait before the first request.

❖ Return:

➜The return value of the first argument function.

❖ Additional:

➜There are two additional features in this function.

1. noRetry: Suppose you throw a custom exception, upon throwing of which, you don't want to retry. For example, if you try to get a response from any website, but received a 404 status code; in that case, you can specify that the request should not be retried.
   Copy
2. waitForInternet: Have you notice this code?
   Copy

   Suppose you are calling an internet API from your local machine, and the internet connection is lost — what happens then? until the connection is restored, it waits.. Your code will not fail. This function is specifically developed with API calling in mind.
