What is the difference between defer and return in Go?

What is the difference between defer and return in Go?

In Go, 'defer' schedules a function call to be run after the function completes, while 'return' exits the function immediately.

Can you give me an example of how defer works?

Sure! If you use 'defer' before a function call, it will execute that call after the surrounding function returns.

What happens if I have multiple defer statements?

They are executed in LIFO order, meaning the last deferred function is called first when the surrounding function exits.

When should I use defer instead of return?

Use 'defer' for cleanup tasks like closing files or connections, ensuring they run even if an error occurs.
