  The performance of reconstruction and calibration of jets and missing
transverse momentum in the CMS Collaboration, together with the latest tools
for pileup mitigation, is presented. The results shown are relative to the data
collected from 2016 to 2018 (Run 2) in proton-proton collisions at a
centre-of-mass energy of 13 TeV. An outlook to the new techniques foreseen for
Run 3 is discussed.
