Panic

Several languages use exceptions for handling errors. However, Go does not use exceptions, it uses something called panic. Panic is a built-in function that causes the program to crash. It stops the normal execution of the Goroutine.

In Go, panic is not the norm, unlike other languages where an exception is a norm. A panic signal indicates something abnormal that is occurring within your code. Usually, when panic is initiated by runtime or the developer, it is to protect the integrity of the program.

Errors and panics differ in their purposes and how they are handled by the Go runtime. An error in Go indicates that something unexpected occurred, but it will not adversely impact the integrity of the program. Go expects that the developer will handle the error properly. The function or other programs will not typically crash if you do not handle the error. However, panics differ in this regard. When panic occurs, it will ultimately crash the system unless there are handlers...
