What is the difference between error handling and logging in Go?

In Go, error handling is about managing errors that occur during execution, while logging is about recording those errors for later analysis.

Can you give me an example of error handling in Go?

Sure! In Go, you typically check for errors after a function call, like this:

result, err := someFunction()
if err != nil {
    // handle the error
}

How does logging work in Go?

Logging in Go can be done using the log package. You can log messages with different severity levels, like this:

log.Println("This is an info message")
log.Fatal(err) // logs the error and exits

When should I use logging instead of error handling?

You should use logging to record errors and important events, while error handling is used to manage the flow of your program when an error occurs.
