Narrative:

While being vectored to ILS 22L at ewr and descending to 3;000; we first received a TCAS TA quickly followed by an RA to level off. I spotted traffic visually; a single engine high wing aircraft traveling northbound along the final approach course. The first officer (first officer) reacted properly to the RA and soon after we got a clear of conflict. I reported the TCAS RA to ATC. The remainder of the approach and landing proceeded without incident.
