Run the first program

If you've already installed Wave in the previous installation document, let's run the first program now!

Create hello.wave file.​

First, create a new file named hello.wave.

Write the code​

Write the following code in hello.wave file:

fun main() {
    println("Hello Wave");
}

Here, fun main() indicates the starting point of the program, and the println function outputs the text to the screen.

Run the program​

Now let's run the Wave program. Open the terminal and enter the following command:

wavec run hello.wave

Check the output​

When you run the program, the following output will appear:

Hello Wave

Now you can check that Wave is installed and working correctly. Congratulations! You have successfully run your first program.
