One of the very first programs you can write to make sure your version of Node is working is the "Hello World" program . There are two ways to create the program: in terminal or in your favorite code editor (eg Visual Studio Code, Vim, etc.). Make sure Node is installed on your machine to get started.

1.In your terminal, type node to start Node.

2. Enter console.log (" Hello World ") into the interpreter and press Enter.

3.Hello World will show the next line ! do not worry if it says "undefined" on the next line. it just means that we do not return anything that or a function.

4. If you also want to create a proof function ! Here & rsquo; how in the terminal:

In your terminal, go to the directory / folder where you saved your file. Use cd and ls to navigate from one directory to another.

Use the hello.js node to run the file. Hello World should appear on the next line ssiva.

If you are using VS Code, the "play" button in the upper right corner will also play the current file and display the output in the lower half of the screen.
