How can I recover from a Go error?

I'm getting a panic error in my Go application. How can I recover from it?

You can recover from a panic in Go by using the recover function within a deferred function. Would you like an example?

Yes, please provide an example of how to use recover.

Sure! Here's a simple example:

package main

import "fmt"

func riskyFunction() {
    defer func() {
        if r := recover(); r != nil {
            fmt.Println("Recovered from:", r)
        }
    }()
    panic("Something went wrong!")
}

func main() {
    riskyFunction()
}

What happens if I don't use recover?

If you don't use recover, the program will terminate and print a stack trace when a panic occurs.

Are there any best practices for error handling in Go?

Yes, it's best to handle errors explicitly using the error return value, and use panic/recover sparingly for truly exceptional cases.
