The code you've shown is not valid Javascript, so you can't get at it in a convenient way.

If what you've shown actually is a mangled version of what otherwise would be valid Javascript, the easiest way is to pull over the value to Perl space:

my $myContests= $mech->eval_in_page('myContests');

print $myContests->{n};
print $myContests->{id};

I keep getting the error: Use of uninitialize value when I run this code. So I'm not sure if the variable "packagedContests" is invalid or if it has something to do with how the page is loading?

use warnings;
use WWW::Mechanize::Firefox;
use DBI;
use Data::Dumper;

    my $url = ("https://www.draftkings.com/contest-lobby");
    my $mech = WWW::Mechanize::Firefox->new();
    $mech->get( $url ) or die("Can't Get Web Page!");

    $contest = $mech->eval_in_page('packagedContests');
  
    print $contest->{n};
    print $contest->{id};
[download]

I love it when a program comes together - jdhannibal

I'm sorry - I should read the documentation closer. The code to fetch the variable should be:

my ($contest, $type) = $mech->eval_in_page( 'packageContests' );
[download]

But you should also use strict; at the top of your program. This would have immediately shown the wrong use of ->eval_in_page, as you get a number back instead of a proper reference.

So myContests could be evaluated and analyzed (if still in page scope!)

Alternatively you could request the DOM node of this script-tag and parse the text with a Perl regex.
