What is the usual way to handle an error returned by a function in Go?

  • Using a panic and recover mechanism
  • Ignoring the error and continuing execution
  • Checking the error value and taking appropriate action
  • Wrapping the error and returning it to the caller
The usual way to handle an error returned by a function in Go is to check the error value and take appropriate action based on the error. This can include logging the error, returning it to the caller, or performing some other error-specific behavior. Ignoring the error is generally discouraged as it can lead to unexpected behavior in the program. The use of panic and recover is reserved for exceptional cases and should not be the primary mechanism for error handling in Go.
