What is the purpose of the 'defer' statement in error handling in Go?
- Defers execution of a function until the surrounding function returns.
- Delays the execution of a function until a specified condition is met.
- Forces a function to immediately return without executing the rest of its code.
- Resumes execution after a panic or a recover call.
The 'defer' statement in Go is used to defer the execution of a function until the surrounding function returns. This is often used in error handling to ensure that certain cleanup or finalization tasks are performed before exiting a function, regardless of whether an error occurred. This helps in maintaining clean and readable code, especially in scenarios where resource management or state cleanup is necessary.
