How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Scripting and Automation with Perl with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Quick Facts about Perl
Perl: The Swiss Army Chainsaw of Scripting Languages
Did you know that Perl was concocted in 1987 by Larry Wall as a fusion potion to blend the best features of sed, awk, and C? Wall, a linguist turned coder, spun up Perl in a cauldron of Unix scripting challenges, giving rise to a tool so versatile it's been dubbed the "Swiss Army chainsaw" of software development. Its first release was December 18th, 1987—talk about a programmer's holiday treat!
Cult Following and the Use of a Camel
Drawing the curtain back to reveal the Perl stage, it's not just the language that’s quirky. Perl has amassed a cult-like following where "There's more than one way to do it" isn’t just tolerated; it's the mantra. Not to forget, Perl's spiritual animal is none other than a camel, thanks to the "Programming Perl" book cover. This hump-backed beast embodies Perl's strength and endurance across the coding dunes.
Evolution from Perl 5 to Perl 7... Skipping Perl 6
Like a magic trick gone slightly awry, Perl 6, now Raku, split from Perl's main family tree, creating its own lineage. Perl 5, the tried and true workhorse, kept galloping along until the big announcement: Perl has planned a time travel jump straight to Perl 7! This is not just a version skip—it's a bid to modernize and streamline, leaving nostalgic code antics for a sleeker future (no Marty McFly needed).
# Simple Perl script to print a greeting
print "Hello, World!\n";

Top 10 Perl Related Tech
Perl 5
At the heart of it all is Perl 5, the quirky chameleon of programming languages, ready to morph into whatever shape your task requires – web scripting, sysadmin, the lot. This linguistic gymnast has been stretching the boundaries of text processing since the 80s, with regular expressions so powerful they've been rumored to solve crossword puzzles in their sleep. Get comfortable with context, scalars, arrays, and hashes; they’re your bread and butter!
# Perl 5 quick example: Reversing a string.
my $string = "Hello World!";
my $reversed_string = reverse $string;
print $reversed_string; # Outputs: "!dlroW olleH"CPAN
Next up is CPAN, the Comprehensive Perl Archive Network – a colossal library of modules so vast, it's like a software buffet. It's the power strip where Perl plugs in to amp up its abilities. Need to parse XML? There's a module for that. Handle a database? There's a module for that too. With CPAN, it’s like walking into a hardware store with your problems and walking out with solutions.
Mojolicious
If you're venturing into web development, Mojolicious is your trusty web framework steed. It's like having a Swiss Army Knife that's also somehow a web server. This real-time web framework is slick, has WebSocket support, and honestly, it's so user-friendly, it practically makes you breakfast in the morning. Non-blocking? Tick. RESTful routes? Double tick. Mojolicious makes the hard stuff look easy.
# Mojolicious "Hello World" example
use Mojolicious::Lite;
get '/' => {text => 'Hello World!'};
app->start;DBI
The Database Interface (DBI) module is the go-to for database interaction in Perl. It's like a universal translator for database languages – Oracle, MySQL, PostgreSQL, you name them, DBI speaks them. It’s the tool you want in your utility belt when database spelunking calls for a safe tether back to Perl land.
# DBI example: Connecting to a database and executing a query
use DBI;
my $dbh = DBI->connect("DBI:mysql:database=testdb", "user", "password");
my $sth = $dbh->prepare("SELECT * FROM mytable WHERE id = ?");
$sth->execute(42);
my @row = $sth->fetchrow_array();
$sth->finish();
$dbh->disconnect();Plack
Plack is to web apps what rocket fuel is to rockets – it launches them. It's a set of tools and a superglue layer between web servers and web applications. Plack takes the nitty-gritty of HTTP handling off your hands, so your code can float gracefully in the application layer without drowning in web server details.
# Example: A simple Plack web app
use Plack::Builder;
my $app = sub {
my $env = shift;
return [ 200, ['Content-Type' => 'text/plain'], ["Hello World"] ];
};
builder { $app };Catalyst
For those who love classic MVC frameworks, Catalyst is there, grand and wise, having seen the web evolve over the years. It’s like the Gandalf of Perl web frameworks – respected, full of wisdom, and with more features than a Swiss Army Knife. It empowers developers to build scalable and maintainable web applications, guiding them through the MVC patterns like a sagely old wizard.
# Catalyst example: The simplest Catalyst "Hello World"
use strict;
use warnings;
use Catalyst::Runtime '5.80';
package HelloWorld;
use parent qw/Catalyst/;
HelloWorld->setup;
package main;
HelloWorld->run;Dancer
Dancer prances into the scene when you're after a lightweight web framework. It's nimble, agile, and allows you to swiftly pirouette around web development tasks. Dancer is brilliant for those quick MVPs and prototypes, where launching yesterday wouldn’t have been soon enough. It doesn't have as many bells and whistles as Catalyst, but boy does it make those simple apps dance!
# Dancer "Hello World" example
use Dancer2;
get '/' => sub {
return "Hello World!";
};
start;Perl Debugger (perl -d)
When code acts up, the Perl Debugger is the stern schoolmaster that gets it back in line. It's the magnifying glass that helps you inspect, disassemble, and understand what your code is really up to. It'll tease out the variables, poke at the subs, and keep your code honest. Remember, it's '-d' for 'detective'!
# Starting the Perl debugger from the command line
perl -de 0Test::More
Behold, Test::More, the guardian of your code's reliability. Infused with enough testing magic to make even the most bug-ridden code quiver in fear. It embodies the "test early, test often" mantra. Simple, powerful, and verbose, it lets you write tests that sing your expected outcomes from the rooftops and shout down failures with relentless zeal.
# Test::More example: Writing a simple test
use Test::More tests => 1;
is(reverse("hello"), "olleh", "Test reversing a string.");Perl Critic
Last, but certainly not least, Perl Critic looms like a stern professor, ready to grade your code. It’s a static code analyzer sternly peering over your shoulder to ensure you adhere to best practices. It doesn't just keep you in line; it teaches you the path to Perl enlightenment, one critique at a time.
# Perl Critic example: Analyzing a Perl script
use Perl::Critic;
my $critic = Perl::Critic->new();
my @violations = $critic->critique("path/to/your_script.pl");
foreach my $violation (@violations) {
print $violation->as_string, "\n";
}
