In Go, what is the role of the 'panic' function in error handling?
- Halts the program and logs the error message.
- Resumes execution after a deferred function completes.
- Terminates the program immediately, unwinding the stack.
- Throws an error message and continues program execution.
The 'panic' function in Go is used to abruptly terminate the program by unwinding the stack. When called, it stops the normal execution flow and starts to panic, which means it walks back up the stack, executing any deferred functions along the way, and then exits the program. Panicking is typically used to indicate that the program has encountered a situation it cannot recover from, such as a critical error or an unexpected condition.
