Returns a String with the status of {job}: "run" job is running "fail" job failed to start "dead" job died or was stopped after running

On Unix a non-existing command results in "dead" instead of "fail", because a fork happens before the failure can be detected.

If in Vim9 script a variable is declared with type "job" but never assigned to, passing that variable to job_status() returns "fail".

If an exit callback was set with the "exit_cb" option and the job is now detected to be "dead" the callback will be invoked.

For more information see job_info().

Can also be used as a method:

GetJob()->job_status()
