Hello, World!

Let’s write your first Z# program — the classic Hello, World!.

Step 1: Create a File

Create a new file called main.zs:

touch main.zs

Step 2: Write the code

Paste the following code into main.zs

import 'z#';

Console.log('Hello, World!');

Process.exit(0);

Don’t worry about the syntax for now — we’ll cover it in the next section.

Step 3: Run the Program

Run:

zs run main.zs

You should see: Hello, World!

🎉 That's it — you’ve just written your first Z# program!
