Why did Go add panic and recover in addition to error handling? [closed]

Answer 1

Because this is more powerful as it allows to create more resilient programs.

In C you can't recover from a NULL pointer dereference.

In Go you can catch it with recover.

This allows for example to create in Go an HTTP server that can catch a NULL pointer dereference when handling a request and return an error 500 instead of crashing the whole server.
