video 1.1 fetch() notes

Filing some notes in case I want to record an extra video to go in between 1.1 and 1.2.
* mentioning `try/catch` as error handling option next step
* pointing out that this is just to demo `fetch()` of course just say ``
* Noting that if you use `return` in `getData()` it’ll come back in the promise as `response.`

No file or test is named. Start by reviewing the fetch() and getData() points in the issue body; done means deciding how to capture the try/catch note, the image example, and the return behavior for the possible video between 1.1 and 1.2.
