Take a look at the main.lua file in the code editor that is placed in the middle of the screen. It’s a Lua program!

When learning a new language, tradition suggests that our first program prints to the screen: Hello, world!.

In Lua, this can be done in a single line:

print("Hello, world!")

Everything inside the double quotes will be printed to the terminal.

The terminal is a window that allows people to interact with a computer program. The terminal is the black panel on the right. It should be blank right now, but we’ll change that in a moment.

Note: Don’t worry if you don’t understand something, everything introduced in this lesson is explained in the rest of this course.
