A simple introduction to JavaScript and the DOM

If you have GIT available, clone this repository using git clone https://github.com/CTEC3905/03-lab-javascript-1.git instead of just downloading it.

You must then create your own repository on GitHub for these files, then change the GIT remote to the GitHub URL for your new repository with the following commands:

• git remote rm origin
• git remote add origin [YOUR_REPO_URL_HERE]

then check your remote is your own repository with:

• git remote -v

This exercise introduces a few fundamental Javascript principles:

• immediately-executed function expressions (stay out of the global namespace)
• event listeners (for capturing user actions)
• DOM manipulation (changing HTML elements and/or their properties)

Read through the comments in the code and try out the suggestions.
