Panic

Several languages use exceptions for handling errors. However, Go does not use exceptions – it uses something called a panic. This is a built-in function that causes a program to crash. It stops the normal execution of the current goroutine where the panic happened and all other ongoing goroutines and shows a stack trace of what occurred.

In Go, a panic is not the norm, unlike other languages where an exception is the norm. A panic signal indicates something abnormal that is occurring within your code. Usually, when a 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...
