On takeoff from EWR Runway (RWY) 04L at approximately 100 feet AGL noted traffic executing go-around/missed approach from RWY 04R. Weather at time was OVC 003; 2SM RA. Traffic was at our 2 O'clock position when first noticed and slightly above our altitude. We ultimately were at same altitude and separated by approximately 500-1000 feet laterally before losing sight of traffic as we climbed into clouds at 300 AGL. ATC issued traffic an immediate right turn to HDG 080 and to climb to 3;000 and then issued our aircraft clearance to fly RWY HDG and climb to 2;000.
After takeoff from EWR 4L on the NEWARK FOUR Departure we spotted close proximity traffic to our right as we were climbing through approximately 200 feet. My best guess is the traffic was about 100 feet above our altitude and 1000 feet laterally. I found out later the traffic was on a go-around from 4R. I do not remember hearing any traffic declaring they were going around. Tower immediately instructed us to maintain runway heading and an altitude of 2000 feet and instructed the traffic to turn right to a heading of 080. We did not receive a TCAS TA or RA which are inhibited on takeoff below 600 feet and 1100 feet respectively.
Flight crew reported sighting close proximity traffic immediately after takeoff from runway 4L at Newark.
