Hello World

Your first VDX program. Starting with v0.0.15, a class wrapper is optional — you can write top-level statements directly.

1. Create a file

Create a file called hello.vdx:

print("Hello, world!");

Or with a class wrapper (recommended for larger programs):

class Hello {
    print("Hello, world!");
}

2. Run it

vdx hello.vdx

Output:

Hello, world!

3. What happened?

• print("Hello, world!"); — prints text to the terminal. Every statement ends with ;
• class Hello { ... } — declares a class named Hello. Classes are optional but recommended for organizing larger programs.

A bigger example

let name = "VDX";
print("Welcome to", name);

print(1 + 1);
print(10 * 3 + 2);

fn greet(who) {
    print("Hello,", who);
}

greet("developer");

Output:

Welcome to VDX
2
32
Hello, developer
