How do I initialize values in a hash without a loop?

Question

I am trying to figure out a way to initialize a hash without having to go through a loop. I was hoping to use slices for that, but it doesn\'t seem to produce the expected resul

Answer 1

So, what you want is to populate the hash using an array for the keys, and an array for the values. Then do the following:

#!/usr/bin/perl
use strict;
use warnings;

use Data::Dumper; 

my %hash; 

my @keys   = ("a","b"); 
my @values = ("1","2");

@hash{@keys} = @values;

print Dumper(\%hash);'

gives:

$VAR1 = {
          'a' => '1',
          'b' => '2'
        };
