How can I recover from errors in Go?

How can I recover from errors in Go?

In Go, you can recover from panics using the recover function within a deferred function. Would you like an example?

Yes, please provide an example of using recover.

Sure! Here's a simple example:

package main

import "fmt"

func riskyFunction() {
    panic("Something went wrong!")
}

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

func main() {
    safeFunction()
}

This will recover from the panic and print the message instead of crashing.

What happens if I don't use recover?

If you don't use recover, the program will terminate when a panic occurs, and you'll lose the current state of execution.
