How We Evaluated the Languages

We used these key factors to assess scripting languages for automation:

1. Learning Curve

We looked at how easy each language is to pick up and use. Python stood out here. The Stack Overflow Developer Survey 2024 found that 25% of developers want to learn Python, making it the most sought-after language for the 5th year running.

2. Speed and Resource Use

We checked how fast each language runs and how much computer power it needs. Lua did well in this area. Tests showed it can be up to 10 times faster than Python for some automation tasks, especially in small devices.

3. Help and Resources

We looked at how much support and information is out there for each language. JavaScript (Node.js) excelled here. As of July 2024, npm had over 2 million packages, giving users lots of tools for automation projects.

4. Working with Other Tools

We checked how well each language works with other software and systems. PowerShell stood out for Windows users. Microsoft reported that PowerShell script use for Azure automation went up by 40% in 2023.

5. Use on Different Systems

We looked at how well scripts can run on various operating systems. Bash did well here. A 2024 survey found that over 70% of DevOps pros use Windows Subsystem for Linux (WSL) to run Bash scripts on Windows for cross-platform automation.

Factor	Top Language	Key Stat

Here's a simple example of what their Ruby code might look like:

orders.each do |order|
  process_payment(order)
  update_inventory(order)
  send_confirmation(order)
end

This code goes through each order, handles the payment, updates what's in stock, and sends an email to the customer.

Tips for using Ruby in automation

1. Use RSpec for testing your scripts
2. Try Chef Inspec for checking your code setup
3. Look at Ruby on Rails for web-related tasks

Here's a simple example of what their Perl code might look like:

use strict;
use warnings;

foreach my $hotel (@hotels) {
    update_price($hotel);
    update_availability($hotel);
    update_description($hotel);
}

This code goes through each hotel, updates its price, checks room availability, and refreshes the description.

Tips for using Perl in automation

1. Use 'use strict' and 'use warnings' to catch errors
2. Try Perl::Critic to check your code quality
3. Use Perl's built-in debugger for troubleshooting

"Using Lua, we cut our game loading time by 50%. Games now load in 5 seconds instead of 10. This made our 150 million monthly players much happier."

Here's a simple Lua code example they might use:

function loadGame()
    loadAssets()
    initializePlayer()
    setupEnvironment()
end

This code loads the game parts, sets up the player, and creates the game world.

Tips for using Lua in automation

1. Use Luarocks to add new tools easily
2. Try LuaFileSystem for working with files
3. Use LuaSocket for internet tasks
