in thread Get most recent data based on a date from an array of hashes.

Note that max_by() can also return multiple max's if it is used in list context.

#!/usr/bin/perl use strict; use warnings; use List::AllUtils qw( max_by ); my $data = [ { acc => 1111, Color => "green", Date => "08-06-2022", Step => "Plat +form" }, { acc => 1111, Color => "black", Date => "01-05-2019", Step => "Plat +form" }, { acc => 1111, Color => "reddish", Date => "03-21-2021", Step => "Pl +atform" }, { acc => 1111, Color => "blue", Date => "10-11-2020", Step => "Platf +orm" }, { acc => 1111, Color => "white", Date => "08-06-2022", Step => "Plat +form" }, { acc => 1111, Color => "red", Date => "03-21-2021", Step => "Platfo +rm" }, ]; my @mostrecent = max_by {join '', (split /-/, $_->{Date})[2,0,1] } @$d +ata; use Data::Dump 'dd'; dd @mostrecent;

Outputs:

( { acc => 1111, Color => "green", Date => "08-06-2022", Step => "Plat +form" }, { acc => 1111, Color => "white", Date => "08-06-2022", Step => "Plat +form" }, )

    This is way ++cool.
    I wasn't aware of List::AllUtils or List::Utilsby in the List:: menagerie

    List::Utils
    List::MoreUtils
    List::AllUtils
    List::SomeUtils
    List::UtilsBy
