Running JavaScript with Node

#

We have our Visual Studio Code Editor and our terminal available to us in our workspace.

To begin, we'll start with an empty folder labeled tinyhouse_v1/ in our editor workspace.

tinyhouse_v1/

tinyhouse_v1/ would be the directory where we build the app for the first part of our course. To get things started we're going to create a subfolder called server within the tinyhouse_v1/ project that would host the server portion of our app. We'll also go ahead and have an index.js file be created within this server subfolder.

tinyhouse_v1/
  server/
    index.js

The node command

#

For our very first attempt, we're going to see how we could use node to run some JavaScript code and the first code we're going to write is a simple console.log message.

We're going to attempt to log something into our terminal console and the first thing we're going to look to log is a simple string that says 'hello world'.

console.log('hello world');

Next, we're going to create two constant variables. We're going to create a variable called one and another called two and assign them numerical values according to the variable name.
