  Recent results in high-multiplicity pp collisions show features similar to
those that are associated with the formation of a quark$-$gluon plasma in
heavy-ion collisions. Investigating the modification of the intra-jet
properties as a function of event multiplicity in pp collisions can provide
deeper insight into the nature of these effects. We will present the recent
measurements of multiplicity dependence of charged-particle jet properties
(average charged particle multiplicity and fragmentation functions) for leading
charged-particle jets. Jets are reconstructed using anti-$k_{\rm T}$ jet
finding algorithm with radius parameter $R$ = 0.4 in the jet $p_{\rm T}$ range
from 5$-$110 GeV/$c$ at midrapidity in pp collisions at $\sqrt{s}$ = 13 TeV
with ALICE.
