I'm trying to teach myself a little more about threading subroutines and I'm confused by the difference of join vs detached. Using the following example can anyone shed some light on the difference?

use warnings;
use strict;

use threads;
use threads::shared;
#use Time::HiRes;

#my $t0 = Time::HiRes::time;  

my @array : shared;
for (1..50) {
    push @array, $_;
}

my $thr = threads->create(\&spawnThread);
my $thr2 = threads->create(\&spawnThread);
my $thr3 = threads->create(\&spawnThread);
my $thr4 = threads->create(\&spawnThread);
my $thr5 = threads->create(\&spawnThread);

$thr->join();
$thr2->join();
$thr3->join();
$thr4->join();
$thr5->join();

#my $t1 = Time::HiRes::time;
#my $elapsed = $t1 - $t0;
#print "\nElapsed Time: $elapsed\n";

sub spawnThread {
    
    for(1..10) {

    my $index = shift @array;
    print "$_ => $index\n";
    }
}
