exit

Built-in function · Available everywhere, with no import

exit ends the program right away. A program also ends on its own when it reaches its last line, so exit is for stopping early.

const answer = input("Continue? ")
if answer != "yes" {
    print("Goodbye!")
    exit()
}
print("Continuing...")

exit(code: Int = 0)

Ends the program with the status code, which other programs can read: 0 means it finished normally, and anything else, up to 255, means something went wrong. Before the program ends, every finally block it is inside still runs.

exit is not an error, so a catch cannot stop it.

Raises when code is not from 0 to 255.
