golang recover panic 流程控制的可达与不可达

--------------------------流程控制可达-----------------------------
package main

import "fmt"

func explode() {
// Cause a panic.
panic("WRONG")

}

func throwPanic(f func()) {
defer func() {
if err := recover(); err != nil {
// Handle our error.
fmt.Println("FIX")
fmt.Println("ERR", err)
}
}()
f()
fmt.Println(" finish")
}

func main() {
throwPanic(explode)
fmt.Println(" reach here ")//可达
}
