Matthew Chmielinski had avoided a jail sentence for a violent assault and for spitting at a police officer.
When officers arrived at the crime scene last May, having been called to a ‘disturbance’, they found the victim outside his flat with ‘significant facial injuries’.
He had been punched and kicked in the head, and a window had been smashed.
Chmielinski was found unresponsive in his victim's bedroom.
Paramedics treated the 21-year-old, who was arrested on suspicion of grave and criminal assault and malicious damage.
He was taken to the hospital, where he spat on a police officer.
Chmielinski pleaded guilty to the three offences in the Magistrate's Court on 2 January and was sentenced by the Royal Court today (21 March)
He has been ordered to do 360 hours of community service, put on a two-year probation order and has been given a restraining order.
DS Jim McGranahan says the police will not tolerate acts of unprovoked violence as a police force or as a society.
"States of Jersey Police will continue to work hard, and in conjunction with the public and victims, to keep our streets and community safe."
