How to catch (recover) panic() error

package main

func main() {
  test()
  print("world after panic")
}

func test() {
  defer func() {
		if err := recover(); err != nil {
			print("catched panic, ha ha ha...")
		}
	}()
	
	panic("noooo")
}

• package main - default package declaration
• func main() { - declare main function that will be launched automatically
• func test() - test function has panic() call and its handler via recover()
• if err := recover() - catch panic via recover()
• print("world after panic") - this should would if panic was catches successfully

group: panic

Example:

package main

func main() {
  test()
  print("world after panic")
}

func test() {
  defer func() {
		if err := recover(); err != nil {
			print("catched panic, ha ha ha...")
		}
	}()
	
	panic("noooo")
}

catched panic, ha ha ha...world after panic
