Testing code performance in Perl, especially when it comes to arrays, can provide valuable insights into its efficiency. The following example demonstrates how to measure the performance of array operations using built-in functions like `timeit` from the `Test::More` module.
use strict;
use warnings;
use Time::HiRes qw(time);
my @array = (1..1000000); # Example array
my $start_time = time();
# Perform an operation on the array
my @squared = map { $_ * $_ } @array;
my $end_time = time();
my $execution_time = $end_time - $start_time;
print "Execution Time: $execution_time seconds\n";
