What is Lua?

Lua stands out as a powerful, efficient, and lightweight scripting language. It's like a chameleon, adapting to various tasks effortlessly. Lua doesn't tie you down with rigid rules; instead, it embraces flexibility. Whether you're into procedural, functional, or object-oriented programming, Lua has you covered.

Setting Up Lua

Before we jump into coding our "Hello World" masterpiece, let's make sure Lua is snugly settled on our system. You can grab Lua from the official website: lua.org/download.html. Follow the installation guide tailored for your operating system, and you're all set.

Writing the "Hello World" Program

Now that Lua is cozy on our machine, it's time to give birth to our first Lua creation. Fire up your preferred text editor and craft a new file named hello.lua. Inside this file, sprinkle the following incantation:

-- hello.lua
print("Hello, world!")

In Lua, print() acts as a magical conduit to the console, whispering messages like "Hello, world!" into existence.

Running the Program

To witness the magic of our Lua spell, summon your terminal or command prompt. Navigate to the enchanted directory where hello.lua resides and chant the following command:

lua hello.lua

If Lua hears your call and is properly attuned, you'll be greeted with the enchanting words:

Hello, world!

Congratulations! You've initiated your Lua adventure with a triumphant "Hello, world!"

Conclusion

In this enchanted journey, we've unveiled Lua's charm as a nimble scripting language and embarked on the ritual of creating the timeless "Hello World" program. This humble script serves as your guiding star, illuminating the path to Lua mastery. May your Lua adventures be filled with joyous coding!
