Hello World!

The print() function takes whatever you put inside the parentheses and displays it as output. When you want to display text, you need to wrap it in quotes to create what's called a string.

Here's the basic syntax:

print("Your text here")

You can use either double quotes " or single quotes ' around your text - both work the same way in Lua.

The traditional first program that every programmer writes is called "Hello World!" and it looks like this:

print("Hello World!")

When you run this code, you'll see the exact text Hello World! appear in the output area. This simple program demonstrates the fundamental concept of producing output in any programming language.
