Explain the purpose of the defer statement in error handling.

  • To handle runtime exceptions
  • To postpone the execution of a function until the end
  • To skip a specific error
  • To stop the execution of a program
The defer statement in Go is used to postpone the execution of a function until the surrounding function returns. It's commonly used in error handling to ensure that certain cleanup or resource release actions are performed, even if an error occurs within the function. This is particularly useful for tasks like closing files or releasing locks. The purpose of defer is to help maintain the correctness and reliability of the program, especially in cases where errors might interrupt the normal flow of execution.
