How would you propagate an error up the call stack in Go?

Use a return statement with the error value.
Use the "panic" keyword.
Use a custom "Error" function.
Use "recover" in the calling function.

In Go, errors are propagated up the call stack by using a return statement with the error value. When a function encounters an error, it can return it to the caller by returning the error value along with the result. The calling function can then inspect the returned error and decide whether to handle it or propagate it further. This allows for clean error propagation without causing panics or interrupting program execution.
