Test the installation

1. Test Node
   To see if Node is installed, open the Windows Command Prompt, Powershell or a similar command line tool, and type node -v. This should print a version number, so you’ll see something like this v0.10.35

2. Test NPM
   To see if NPM is installed, type npm -v in a terminal. This should print NPM’s version number so you’ll see something like this 1.4.28.

3. Create a test file and run it
   A simple way to test that node.js works is to create a JavaScript file.

Create a new file and name it hello.js, and just add the code console.log('Node is installed!');

To run the code simply open your command line program, navigate to the folder where you save the file and type node hello.js.

This will start Node and run the code in the hello.js file. You should see the output Node is installed!
