What is the difference between panic and error in Go?

What is the difference between panic and error in Go?

In Go, an error is a value that indicates a problem that can be handled, while a panic is a runtime error that stops the normal execution of a program.

Can you give me an example of when to use panic?

You should use panic for unrecoverable errors, like when your program is in a state that it can't continue, such as a failed assertion.

What about using error? When should I return an error instead?

You should return an error when the caller can handle the situation, like when a file can't be opened or a network request fails.

Is it possible to recover from a panic?

Yes, you can recover from a panic using the recover function, which allows you to regain control of the program.

What are some best practices for error handling in Go?

Best practices include always checking for errors, using custom error types, and avoiding panics for expected errors.
