jess.application: { exit }

Also require('@jess/application'). What an application's code asks of the host running it. A script under jess run or a command target ends when it returns, so there is nothing to ask, and exit errors.

jess.application.exit§

jess.application.exit(status: number?) -> ()

Asks the host to stop after the current frame, with status (0 without one) as the process's exit status. It returns; the frame finishes, then the shutdown handlers run and the application is torn down. A later call in the same frame replaces the status. A restart forgets the request.

Errors: application.exit: the status is an integer from 0 to 255, not <status>; application.exit: needs an application host; jess run, jess test, and command targets end when their script returns; in a worker, application.exit is for the domain's own code; a worker asks the domain in a message.
