Deliverables:

1. PPT highlight and explaining the most important parts, screenshots showing the code, and what it does ( ie. a screenshot also from the web page)
2. Have HTML files ready to share demonstrating the code.

I have been asked “How many examples should I have”?

And there is no one answer. You should convey the “major important” aspects. Absolute bare minimum is 5 code examples but there is no need to kill us with redundant code that only has small changes.
