Will Needs These Questions Answered!

Thanks for checking out my new project. Here's how it works:

1. As I work on new JavaScript skills, I often hear/read/encounter new things that I don't understand.
2. I'll add those questions to the 'Issues' section of the repository here
3. If you can answer a question, create a fork of the repo and answer it in a markdown file
4. Name your markdown file like this: [ issuenumber].md
5. Submit a pull request with a message like this: closes #[issue number]
