Hello, world!

So now, let's write our first "Hello, world!" program using Node.js

• Create a new directory of your choice

  mkdir hello-world

• Navigate to newly created directory

  cd hello-world

• Open your preferred text editor. You can use editors like Visual Studio Code, Atom, Sublime Text, or any other editor of your choice. I'll be using vim (opens in a new tab) / neovim (opens in a new tab) through out the workshop.

  If you are using Visual Studio Code you can run following command.

  code .

• Create a new file in your text editor and save it with the name hello-world.js. And write the following code:

  console.log("Hello, world! 0/");

• I'll create the file using the following bash command:

  echo "console.log('Hello, world! 0/');" > hello.js

• Let's run the script

  Open your terminal or command prompt. This is where you'll run your Node.js script. Type the following command and press enter:

  node hello.js

  Output:

  $ node hello.js
  Hello, world! 0/

Now that you've conquered the mighty 'Hello, World!' in Node.js, you're officially a JavaScript wizard!
