Query: On (co)ends in $\infty$-categories   In this short note we prove that two definitions of (co)ends in
$\infty$-categories, via twisted arrow $\infty$-categories and via
$\infty$-categories of simplices, are equivalent. We also show that weighted
(co)limits, which can be defined as certain (co)ends, can alternatively be
described as (co)limits over left and right fibrations, respectively.
