Node setup

Okay, enough said. Let's go ahead and install Node, which comes bundled with npm:

1. Go to https://nodejs.org and download the latest stable release of Node:

2. Here, I would choose v6.10.3, the one recommended for most users.
3. Once that is installed, open up your terminal and run node -v just to confirm the installation:

4. You can also confirm that npm has been included by running npm -v.

Just to reiterate, Node is a JavaScript runtime used to execute JavaScript outside of the browser, and npm is a method of managing modules of JavaScript code. We won't be working with Node directly in this book, but we will be using npm a lot.
