The built-in recover function can be used to regain control of a panicking goroutine and resume normal execution.. a call to recover stops the unwinding and returns the argument passed to panic. ; if the goroutine is not panicking, recover returns nil. because the only code that runs while unwinding is inside deferred functions, recover is only useful inside such functions.
